Peter Louis is an Australian former professional rugby league footballer and coach. He played in the New South Wales Rugby Football League premiership for Sydney's Canterbury-Bankstown club in the 1960s as well as in the country for Woy Woy's club. Louis then started coaching there before returning to Sydney, eventually becoming head coach of the North Sydney Bears in the 1990s. After almost seven seasons he became the National Rugby League referees' coach.
Louis started his playing career in Woy Woy before moving to Sydney and joining NSWRFL premiership club, Canterbury-Bankstown in 1968. He played mostly in reserve grade, with a handful of appearances in first grade during the 1969 NSWRFL season. Part-way through the 1970 season Louis returned to Woy Woy where he was captain-coach. He guided the club to a first grade premiership.
Louis returned to Sydney and had success coaching in the New South Wales Rugby Football League's reserve grade for the Parramatta Eels from 1984 to 1989 and the North Sydney Bears from 1990. He replaced Steve Martin as head coach of North Sydney for the 1993 NSWRL season.
After falling just outside the top five play-off group in his first year, he helped the Bears come to within one win of the minor premiership for the 1994 NSWRL season and was named coach of the year at the Dally M Awards. Under Louis Norths then came within one match of the 1996 ARL season's grand final.
The following season in 1997, Louis coached Norths to a 4th placed finish. North Sydney reached their 4th preliminary final in 7 years but once again fell short of an elusive grand final appearance losing to the Newcastle Knights. With less than 10 minutes to play, Norths had scored a try through Michael Buettner which gave captain Jason Taylor the chance to kick a goal which would give Norths a 14-12 lead.
Taylor a normally reliable goal kicker missed the conversion. Newcastle then went on to kick a field goal and score a try right on the full time siren to win the match 17-12.
Norths again reached the play-offs in the 1998 NRL season but were eliminated after losing to Parramatta and Canterbury-Bankstown in consecutive weeks.
At the end of his coaching career with Norths, Louis had the second highest win percentage out of anyone who had coached the club before him except for 1921 & 1922 premiership winning coach Chris McKivat.
