Society for Libertarian Life (SLL) was one of the early libertarian student organizations that eventually charted chapters and had a nationwide presence in the United States. Founded in 1973 at California State University, Fullerton (CSUF), SLL was considered one of the largest and most active libertarian organizations along the West Coast. By 1980, it was reported to have 2,000 members.
