Peter Ryan is an Australian former professional rugby league footballer who played as a lock in the 1950s and 1960s.
Ryan was born in Ipswich, Queensland but moved down to Sydney at a young age and played his junior rugby league in the Newtown area before being graded by the club in 1953.
In 1954, Ryan was part of the Newtown side which claimed the minor premiership and made the grand final that year against South Sydney.
In 1955, Newtown again claimed the minor premiership and the club qualified for their second consecutive grand final against the same opponent.
In 1961, Ryan moved back to Sydney and joined perennial strugglers Parramatta and in his first year the club finished last on the table.
