Temple United FC was brought about due to its proximity between the larger cities of Austin, San Antonio, Houston and Dallas and owner Jeremiah Connelly wanted the growth that the city of Temple has seen in recent years to be the catalyst for bringing a recognised men's adult team to the area.

After seeing this massive progress in the past few years, particularly in the West Temple area, with a population of about 70,000+ the time was right to implement a plan to bring minor league soccer to the city.

On March 11, 2015, owner Jeremiah Connelly joined TPSL League President Brendan Keyes and Temple, Texas city Mayor Danny Dunn to unveil the club crest at Lions Park Soccer Complex.

On August 31, Temple United rolled out a promotional video with the launch of the club's first ever full black and white playing kit.

Other new clubs to the league were Austin Lonestrikers, Brownsville Bravos, San Antonio Generals and Dallas Clash.
