Head-Royce's mascot is a
Jayhawk named Tuffy. The high school competes as a member of the
Bay Counties League - East (BCL East). The
middle school competes as a member of the
Bay Area Interscholastic Athletic League (BAIAL). Its rival is
The College Preparatory School, commonly known as 'CPS'. Athletic facilities on campus include the Paul Chapman Pavilion (commonly referred to as "the gym") for basketball and volleyball, three tennis courts (each named), and the Farley Field with the Jesse Becherer Diamond for soccer, baseball, softball, and lacrosse. Head-Royce also has several small practice basketball courts spread around campus. A new drainage system was installed underneath the field in the winter of 2005–2006 to prevent mud patches which had become a problem. The school has also installed a running path on a hill above the field which can be used for recreational running. The field is now made of turf. A swimming pool is on campus for lower school swim lessons, PE classes, and the swim team, but it is not of regulation size and therefore does not host many meets. The golf team plays at Lake Chabot Golf Course, which is near the school. No plans to improve the athletic facilities have so far been revealed in the master plan. In the 2005–2006 school year, the middle school varsity boys teams (high school class of 2010) went undefeated and won the championship in all three of their sports (soccer, basketball, and baseball). This is the first time in league history that the same school has won all three championships
and gone undefeated in the three sports. The high school men's varsity basketball team and women's varsity soccer team have won the
BCL championship six years in a row. In the 2006 season, the women's varsity volleyball team won the BCL championship. The men's varsity soccer program has been extremely successful with multiple BCL championships and two
NCS Championship appearances in the last 4 years. The men's varsity volleyball program were BCL champions in 2006 and 2007 and came in second in NCS in 2006. In 2009, the men's varsity baseball program won the NCS Championship. In 2010 the men's varsity soccer, basketball, and tennis programs all won the BCL championship. The 2012–2013 women's varsity soccer team made history by advancing all the way to the NCS Championship game. In 2016, the women's varsity volleyball team won the CIF State Division V championship, the first statewide team championship in the school's history. In 2017, the men's varsity soccer team won the North Coast Sectional (NCS) Division 2 title vs. Making Waves Academy by a score of 2-1. It was the first men's varsity soccer title win in school history. The Jayhawks ended the season 18-1, and ranked as the top men's team in the state of California for the fall soccer season . They won again in 2018 as well. In 2022-2023, the men's varsity soccer team won the North Coast Sectional (NCS) Division 1 title vs, Making Waves Academy by a score of 2-0. It was the 150th win for Jayhawk coach John Miottel, and the third title in school history. The Jayhawks ended the season 16-3-2, ranked number 3 in California for the fall soccer season. There was even a documentary made about this historical soccer season, featuring multiple seniors that season. The team featured many players who would go on to continue their soccer careers in other facets, with some playing division 1 - division 3 soccer as well as semi-pro and low tier professional leagues. In 2025-2026, the men's varsity soccer team won the North Coast Sectional (NCS) Division 1 title vs Arcata by a score of 4-0. It was the fourth title in school history. It would also be the fourth title for Jayhawk head coach John Miottel. While it was easier competition, as most good teams had moved to the winter season, the Jayhawks still finished 17-3. This was good enough to be ranked number 1 in California for the fall soccer season.
