The Union College Tennis Courts serve as the home of the Union College men's and women's tennis programs. The teams utilize eight on-campus tennis courts for daily practice and match play, hosting the annual Union College and Garnet Charger Invitationals each September as well as several dual matches during both the fall and spring seasons. The facility received its first main renovation in 2017 with the installation of lights, allowing for night practices and offering the campus community evening hours as well. The main six courts also were resurfaced in October 2024 thanks to a gift from the Chi Psi tennis supporters. Live streaming was added to all eight courts in May 2026. When not being used by either tennis teams, the Union College Tennis Courts are available to the college community on a first-come, first-serve basis.
