Texas State University–San Marcos

Texas State University–San Marcos, often referred to as Texas State University, Texas State, or TxState (it actively discourages the use of "TSU") is a doctoral degree granting university located in San Marcos, Texas. Texas State is the largest institution of the Texas State University System, the fifth largest university in Texas, and one of the 75 largest universities in the United States.

As the university's student population has grown -- from 303 in 1903 to 29,125 in 2008 -- the campus, too, has expanded, and today consists of a 457 acre main campus and 5038 acre more in recreational, instructional, farm and ranch land. Texas State is also the lead institution of a multi-institution teaching center offering undergraduate and graduate programs in the greater north Austin area. There are 1,586 Texas State students enrolled at the Round Rock Higher Education Center (RRHEC).

Texas State University is also the only university in the state of Texas to have a former President of the United States as an alumnus. President Lyndon B. Johnson graduated from what was then Southwest Texas State Teachers College in 1930 with a bachelor of science in history with a permanent teaching certificate. After his graduation, Johnson returned to the Texas State campus many times, both as president and in his retirement years. In 1965, he returned to his alma mater to sign the Higher Education Act, which opened the doors of higher education to many who could not previously afford it.

Texas State's Round Rock campus serves as the location for the fictional school TMU (Texas Methodist University) in the NBC TV series Friday Night Lights. Bobcat Stadium in San Marcos is used for TMU's football stadium.
