McCauley and Meyer Barns, Historic barns in Yosemite National Park, United States.

McCauley and Meyer Barns are three agricultural structures in Yosemite, consisting of one McCauley barn and two Meyer barns, each displaying different construction techniques and building methods. They feature wooden frame structures with log cribwork cores and metal roofs that replaced the original wooden shingles.

The McCauley barn was constructed in 1883 by James McCauley, an Irish immigrant who owned hotels in Yosemite Valley. It formed part of a winter residence complex that reflected early agricultural settlement in the park.

The buildings showcase the Mormon Pole Barn style, a construction method that emerged in California's Genesee Valley during the 1850s and remains visible in their handcrafted construction today.

The barns stand in the Foresta area of Yosemite National Park, in Mariposa County, and are reached by car or on foot via trails. The ground around them is level. Weather changes quickly at this elevation, so bring sturdy footwear and layers, especially in the colder months.

These structures rank among the only authentic homesteader buildings within Yosemite National Park that have kept their original architectural features intact. They showcase important examples of early life beyond the park's tourist centers.
