Texas Technological College Dairy Barn, Agricultural learning facility at Texas Tech University, Lubbock, United States.

The Texas Technological College Dairy Barn is a stuccoed American Craftsman building designed by Fort Worth architect W. C. Hedrick with Agricultural Dean A. H. Leidigh and Professor W. L. Stangel, and it has a hay hood. A freestanding grain silo stands beside it. A $3.5 million restoration announced in 2017 was unveiled on October 16, 2020.

The Texas Technological College Dairy Barn was built in 1926–27 to plans by Fort Worth architect W. C. Hedrick, with input from Agricultural Dean A. H. Leidigh and Professor W. L. Stangel. It taught dairy students for 40 years; until 1935 they brought their own cows to campus and sold milk through the Student Dairy Association. The university moved its dairy operations elsewhere in 1967 and abandoned the barn, which was listed on the National Register of Historic Places in 1992 after student fundraising from 1990 to 1992.

The barn demonstrates how agricultural education operated in the early 1900s, with hands-on learning at the center of daily activities. Visitors can see the spaces where students performed routine tasks like milking and animal care.

The barn is located on the Texas Tech campus and is easy to reach when walking through the grounds. Visitors should explore the surrounding area to fully appreciate the building's architecture from different angles.

Until 1935, students brought their own cows to campus and sold milk and dairy products through the Student Dairy Association. After 1927 the Dairy Manufacturers department sold milk and ice cream to Lubbock residents and college cafeterias. The barn has a hay hood, a projecting roof feature above the hay door.
