Wyoming’s sweeping landscapes—where jagged peaks meet rolling sagebrush plains—have long nurtured some of America’s most storied ranches. These vast spreads blend frontier grit, ecological stewardship, and modern innovation, from generations-old cattle brands to guest lodges beneath the Tetons. Measured here by contiguous acreage, this countdown explores the Top 10 Largest Ranches in Wyoming, diving into their origins, hidden gems, and the enduring legacies etched into wind-sculpted grasslands and river bottom meadows.
#1: Pitchfork Ranch (511,000 acres)
Stretching 511,000 acres east of Pinedale, the Pitchfork Ranch was founded in the 1920s by homesteader Jack Anderson and later expanded by the Hornbeck family into a wildlife-friendly cattle operation. Its sunburned sagebrush flats transition to aspen-lined canyons where elk rut and rare Wyoming toads breed in restored wetlands. Over 80 solar-pumped water points serve rotating herds of Black Angus, enhancing rangeland health and bolstering populations of pronghorn and sage grouse. Scattered across the landscape are century-old trapper cabins and a forgotten graphite drill site, silent reminders of Depression-era survival. Each summer, youth workshops revive cowboy traditions—branding, roping, and campfire cookouts—while guest cabins on spring-fed ponds offer fly-fishing and starry-sky solitude. Under the Hornbecks’ fifth generation, the Pitchfork balances beef, biodiversity, and heritage tourism beneath Wyoming’s endless sky.
#2: Stewart Family Ranch (480,000 acres)
The Stewart Family Ranch spans 480,000 acres along the North Platte River, its ancient riparian bottomlands cradling waterways vital to irrigated alfalfa fields and cattle pastures. Established in 1904 by Scottish immigrant James Stewart, the ranch’s original log homestead still overlooks one of 70 pivot-irrigated circles dotting the grasslands. Beneath cottonwood groves, paddlers launch canoes to spy beavers damming side channels. Farther afield, drought-resilient crested wheatgrass pastures yield winter feed. The Stewarts introduced wagyu-Angus crossbreeds in the 1980s, pioneering high-marble beef marketed at Denver dining tables. Hidden among rolling dunes lie fossils of ancient camels and horses, unearthed by erosion and cataloged by University of Wyoming paleontologists. Each fall, the ranch hosts a Heritage Rodeo where contestants compete in steer wrestling before a backdrop of sun-bleached buttes, weaving community roots into the high-plains tapestry.
#3: Hat Five Ranch (456,000 acres)
Named for a distinctive five-pointed headland, the Hat Five Ranch covers 456,000 acres south of Riverton. Founded by tribal cattleman Tom Yellowtail in 1928, the ranch blends Native American stewardship with commercial beef production. Its headquarters—an adobe-style lodge—overlooks expansive sage steppe where summer herds graze under migrating hawks. Yellowtail’s descendants maintain treaty rights allowing Tribal members to hunt elk on the ranch’s winter ranges, preserving centuries-old subsistence traditions. Along a hidden tributary of the Wind River, cottonwoods arch over fly-fishing pools stocked with cutthroat trout for guest lodges tucked into juniper-scattered hills. In the 1970s, ranch hands discovered a trove of Fremont petroglyphs along a dry gulch—now protected through co-management with regional tribes. Today, the Hat Five balances treaty rights, tourism, and heritage beef programs under wide Wyoming skies.
#4: Three Crow Ranch (430,000 acres)
Three Crow Ranch spans 430,000 acres of mixed sagebrush flats and foothill breaks in west-central Wyoming. Established in 1912 by Jackson Hole entrepreneur Robert Hilliard, it passed to the Crow family in the 1940s, lending its name to the nearby mountain peak visible from the main ranch house. Its mosaic of riparian corridors and ridgeline pastures supports a herd of Hereford cattle alongside reintroduced bison—part of a 1990s conservation initiative. A forgotten homesteader cabin lies in Buckskin Canyon, where solitary visitors find hand-hewn beams and rusted plowshares beneath cliff overhangs. Seasonal roundup still follows original horse trails across the Crazy Woman Creek drainage, while weekend guests at the converted bunkhouse enjoy guided birdwatching and stargazing programs. Three Crow exemplifies half-century ranch tradition meeting modern habitat restoration under Wyoming’s expansive horizon.
#5: Foley Ranch (400,000 acres)
The Foley Ranch’s 400,000 acres span the Wyoming Basin’s sagebrush seas, founded by Irish immigrant Patrick Foley in 1898. Foley’s stone corral complex—built from local volcanic outcrops—survives alongside a 1905 bunkhouse where cattle drives began at first light. Today, the family’s fifth generation oversees rotational grazing designed to mimic historic bison patterns, supporting endangered sage grouse leks each spring. On remote ridges, energy-independent cabins use passive solar design, offering corporate retreats emphasizing mindfulness in high desert solitude. Near a hidden playa lake, volcanic tuff cliffs shelter nesting golden eagles, documented in a long-term ornithological study. Foley’s ranch bridges Old World immigrant grit with twenty-first-century sustainability beneath Wyoming’s boundless skies.
#6: J Bar L Ranch (375,000 acres)
Founded in 1876 by frontier trailblazer Lucian N. Maxwell, the J Bar L Ranch today covers 375,000 acres of Red Desert tablelands and mountain draws. Its headquarters—once Maxwell’s trading post—occupies a wind-scoured bench above the Sweetwater River’s wind-sculpted narrows. The Laramie Mountains frame panoramic sunsets, while hidden alkaline basins attract migrating shorebirds. In winter, geothermal-fed springs beneath the ranch lodge maintain open-water refuges for trumpeter swans. The Maxwell lineage’s ranch-horse breeding program remains celebrated at national cutting competitions. Along an old Dutch Flat stage line route, rare desert fossils of brontotheres and three-toed horses emerge from sandstone beds, inspiring paleontology camps. J Bar L blends frontier history with modern cattle genetics under Wyoming’s clear-skied expanse.
#7: Green River Land & Cattle (350,000 acres)
Encompassing 350,000 acres east of the Bitterroot Range, Green River Land & Cattle traces roots to 1883 sheep baron William LaPierre. Today, the ranch diversifies across sheep, cattle, and sunflower crops irrigated from the perennial Green River. Its colossal green-topped pivots contrast with sagebrush hillsides, while historic rock-walled sheep corrals—built by Basque herders—still host annual shearing festivals. Wildlife fences along major drainages allow mule deer migration, and a wildlife observation tower overlooks river meanders where beavers maintain dam networks. The ranch’s agritourism program includes sunflower labyrinth trails and on-farm sheepherding demonstrations. Green River Land & Cattle marries ranching innovation with cultural heritage in the lushest high-desert valley of Wyoming.
#8: Pitchfork Cattle Company (330,000 acres)
Not to be confused with its northern neighbor, Pitchfork Cattle Company spans 330,000 acres in southeast Wyoming’s Thunder Basin. Founded in 1901 by homesteader sisters Anna and Ella Thompson, the ranch still operates under the Thompson name. Its split-rail fences and turn-of-century stone springhouses evoke early settler life, while modern pivot-irrigated alfalfa circles support both cattle feed and bobwhite quail habitat. On a remote hilltop, Native American petroglyphs—recently documented by archaeologists—remind the family and guests of millennia-old desert occupation. Thompson family reunions gather around a restored 1912 bunkhouse, celebrating 120 years of female helm in ranch management. Pitchfork Cattle Company exemplifies resilience and innovation beneath Wyoming’s wild skies.
#9: Diamond S Ranch (315,000 acres)
The Diamond S Ranch covers 315,000 acres along the eastern slopes of the Black Hills—an outlier among Wyoming’s prairies. Founded in 1910 by economist Sanford Strongman, its forestry-style lodge draws architects for timber-frame tours. The ranch’s irrigated meadows yield premium hay, while upland dryland wheat trials support rotation with cattle grazing. On windy ridges, wind turbines supplement ranch income, part of a family commitment to renewable energy since the 1980s. Underground, limestone caverns house an underground wine cellar cooled by constant 50°F temperatures—an unexpected enclave beneath rolling hills. As a working farm, wildlife refuge, and renewable-energy pioneer, Diamond S represents a multidimensional ranching legacy.
#10: Elk Mountain Ranch (300,000 acres)
Rounding out the list, Elk Mountain Ranch encompasses 300,000 acres near its namesake peak, where native elk herds roam river valleys and aspen draws. Established in 1895 by banker Charles Van Natter, the ranch introduced predator-management programs in the 1930s to balance wolf and pronghorn populations. Its sprawling headquarters includes a hand-hewn log lodge—which hosted Teddy Roosevelt on a hunting trip—and restored stagecoach routes connecting remote ghost-town saloons. Each fall, the ranch’s hunting camps revive early 20th-century guiding traditions under canvas wall tents. Elks traverse reclaimed beaver ponds along the North Platte tributaries, while botanists study rare gentian blooms on alpine benches. Elk Mountain Ranch blends wildlife conservation, historic preservation, and guest-lodging experiences under the open, storied skies of southern Wyoming.
