Patrick Denis Marleau (born September 15, 1979 in Swift Current, Saskatchewan) is a Canadian professional ice hockey player for the San Jose Sharks of the National Hockey League. Marleau is the all-time Sharks leader in points and has played his entire NHL career with the Sharks since being drafted second overall in the 1997 NHL Entry Draft.

Patrick grew up on his family farm near Aneroid, Saskatchewan. Most media guides incorrectly list his birthplace as Aneroid instead of Swift Current (Aneroid does not have a hospital).

Patrick Marleau's junior hockey career took him to the Seattle Thunderbirds of the Western Hockey League (WHL) where he played two seasons. In his rookie campaign in 1995–96, Marleau exploded onto the scene in Seattle tallying 32 goals and 74 points, leading his team to a playoff loss to the defending Memorial Cup champion Kamloops Blazers featuring future NHL star Jarome Iginla. The series ended 4-1, but Seattle took 3 of the losses to overtime before the Blazers won.
