The merged university inherited UTPA's
Division I membership; most of the athletic facilities are located in Edinburg. They have membership with the
Southland Conference, having left the
Western Athletic Conference in 2024. Only the men's soccer and women's swimming programs still compete in the WAC. On 1st May, the women’s tennis team won the institution's first WAC Tournament Championship en route to its first NCAA Tournament appearance. On November 19, 2016, the UTRGV women's volleyball team defeated the Utah Valley women's volleyball team, making them the Western Athletic Conference (WAC) Volleyball Champions of 2016.
Mascot The choice of a new university nickname was met with some contention from members of the communities of the two merged schools. UTPA supporters, the larger of the two merged schools, argued for keeping the UTPA nickname, Broncs, while UTB supporters wanted a nickname new to both merged schools. UTPA Alumnus Alex Del Barrio created a petition to "Say No To Vaqueros" that garnered over 11,000 signatures after the announcement was made. Several local city councils also passed resolutions in support of one option or the other. The suggestion for Vaquero was inspired by the UTPA student Studio Art projects, where the Toro and Vaquero were the most popular projects. Bailey also recommended school's athletic colors be UT System orange, green (formerly the secondary color of UTPA), and blue (formerly the secondary color of UTB). Nevertheless, the UT System Board of Regents approved the recommendation the following day, making Vaqueros the fifth NCAA Division I nickname that is a Spanish language word after the
Cal State Northridge Matadors,
UC Santa Barbara Gauchos,
San Diego Toreros, and
New Mexico Lobos. Bailey considered the decision "final" following the approval by the board of regents. About 500 students protested against the Vaquero mascot on the UTPA campus on 13 November 2014. A petition calling for Bailey's immediate resignation garnered more than 700 signatures. Articles of impeachment were filed against the Student Government President Alberto Adame and Vice President Carla "Fernanda" Pena by Jonathan Lee Salinas (Senator at Large '14–'15) partly for their roles in the mascot committee, though the impeachment process was ended due to insufficient evidence. Following the protests, the UT System issued a press release supporting the "Vaquero" decision. At the height of the controversy in November 2014, Texas legislator
Terry Canales suggested he was considering filing a bill requiring UTRGV to abandon the Vaquero nickname. in January 2015. If passed, the legislation would require UTRGV to hold a student election for the athletics nickname, with "Broncs" and "Ocelots" on the ballot. The mascot design was revealed in February 2015. The logo features an orange faced rider in green on a navy blue and green horse. The logo features an outline of Texas in the negative space between the legs of the horse. In June 2019 the new design for the Vaquero mascot was revealed. The new costumed version was voted on and created by UTRGV students. ==Notable alumni (including UTPA and UTB/TSC)==
