The Ramsey High School Rams compete in the Big North Conference, which is comprised of public and private high schools in Bergen and Passaic counties, and was established following a reorganization of sports leagues in Northern New Jersey by the New Jersey State Interscholastic Athletic Association (NJSIAA). Prior to the 2010 realignment, the school participated in the North Bergen Interscholastic Athletic League (NBIL/NBIAL). With 642 students in grades 10-12, the school was classified by the NJSIAA for the 2019–20 school year as Group II for most athletic competition purposes, which included schools with an enrollment of 486 to 758 students in that grade range. The football team competes in the American Red division of the North Jersey Super Football Conference, which includes 112 schools competing in 20 divisions, making it the nation's biggest football-only high school sports league. The school was classified by the NJSIAA as Group II North for football for 2018–2020. Most sports have both a Varsity and a Junior Varsity team, and many sports have Freshmen teams. (Inclusion of "boys"/"girls" designates two distinct teams, even if both practice together.)
