Weslaco High School

Weslaco High School is a four-year public secondary school the Weslaco Independent School District in Weslaco, Texas. It was founded in 1921, the same year that the school district was established after successful petitioning to separate from nearby city Donna and their district. Upon construction of the full time building (located on the corner of South Iowa Avenue and 7th Street) in 1923, the building was utilized for decades as the major high school until 1973. The current building on Pike Boulevard was built in 1973 while the old high school and junior high buildings were eventually preserved and utilized for one of Weslaco's middle schools. Weslaco High remained the only major high school in Weslaco until the construction of Weslaco East High School in the fall of 2000, although Weslaco High housed senior students until the 2003-2004 school year. For the 2009–2010 school year, Weslaco High School was a TEA "Recognized" School. The high school has won one state championship, doing so on June 1, 2024 when they won the UIL 6A Softball Championship Game.
