Tri-County Athletic Association
# Tri-County Athletic Association

The Tri-County Athletic Association (TCAA) is a high school athletic conference in California affiliated with the CIF Southern Section. Established in 2006, the association is an amalgamation of the Tri-Valley League and the Frontier League. The TCAA uses a system of promotion and relegation to place each school's teams, by sport and gender, into either league for a two-year period based on performance. As of the 2018–19 school year, the association is composed primarily of private schools located in Santa Barbara and Ventura counties.

In 2018, five public-school members of the TCAA left to form the Citrus Coast League. Santa Clara High School, a private Catholic school, also joined that league for football only.
