The 1973 Manly-Warringah Sea Eagles season was the 27th in the club's history since their entry into the then New South Wales Rugby Football League premiership in 1947. Manly went into the 1973 season as the reigning premiers having won the 1972 Grand Final defeating Eastern Suburbs 19-14.

As they were in 1972, the 1973 Sea Eagles were coached by former Australian international and Manly fullback Ron Willey. Captaining the side was long serving hooker Fred Jones. The club competed in the New South Wales Rugby Football League's 1973 Premiership season and played its home games at the 25,000 capacity Brookvale Oval.
