McQueeney is a census-designated place (CDP) in Guadalupe County, Texas, United States. The population was 2,527 at the 2000 census. It is part of the San Antonio Metropolitan Statistical Area. German settlers first moved to the area around 1870. When the Galveston, Harrisburg & San Antonio railroad was built through the area in 1876, the stop was named Hilda. In 1900, a local businessman, C. F. Blumberg, built a general store east of the rail stop. Hoping to get the railroad to move the stop from Hilda to his store, Blumberg called the site McQueeney, in honor of the local railroad superintendent. The railroad was not persuaded, but the Post office that opened in 1900 was called McQueeney. Lake McQueeney was created in 1925 by damming the Guadalupe River. Treasure Island, a Wealthy enclave of homeowners on Lake McQueeney, has flooded several times, most notably in 1972, 1998, and 2002.
