Paul Sironen (born 23 May 1965) is an Australian former professional rugby league footballer of Finnish descent[2] who was a prominent Second-row forward for the Balmain Tigers during the late 1980s, and early 1990s.

He was part of the team that played in successive Grand Finals in 1988 and 1989, and included other representative players Steve "Blocker" Roach, Wayne Pearce, Benny Elias and Garry Jack.

He made a number of appearances for both New South Wales in State of Origin, and also for Australia, and has been named as part of the Wests Tigers Team of the Century.

In total he made fourteen appearances for New South Wales from 1989 to 1994, although he failed to score a single point in his State of Origin career.

In his first season in professional rugby league, Sironen was called up to the Australian squad to play against Papua New Guinea and a test match against France, as well as being selected for the 1986 Kangaroo Tour.

Sironen was selected for the 1992 Rugby League World Cup final, played at the famous Wembley Stadium in London in which Australia defeated Great Britain 10–6.

He was involved in controversy, after being hit by an elbow in a club game against Wigan at Central Park by British forward Barrie McDermott, and later in the tour was sent off in the match against St. Helens.

Coach Bob Fulton had originally dropped Sirro from the side that lost 8–4 at Wembley, but he got a recall due to an injury to David Fairleigh.
