William Wayne Paul (1939–1989) was an American martial artist, educator, psychologist and social/political activist.
Born in Nevada County, California, Bill Paul lived in three group homes and attended four high schools during adolescence.
Between 1962 and 1964 he worked as a bouncer at Pierre's Bar in San Francisco's North Beach area.
A keen photographer, he documented clashes between police and student protesters during the unrest at the San Francisco State University and was later reported to have defended Vietnam War protesters from assaults by angry onlookers during peace marches in San Francisco.
Although a self-avowed pacifist with regards to violence as an instrument of state policy, he was notably drawn to interpersonal conflicts and he continued to work as a bouncer at several gay bars in San Francisco.
