John Arne Semundseth Riise (born 24 September 1980 in Molde, Norway) is a Norwegian footballer who currently plays as a left wing-back for Fulham and the Norwegian national team. Riise spent seven years playing for Premier League side Liverpool before moving to Roma in 2008. He is the older brother of Bjørn Helge Riise, who is his team-mate at Fulham.

Riise began his career in his homeland with Aalesund. After a single season as a senior player for the club, he moved abroad in 1998, playing the formative years of his professional career with French club AS Monaco. When Aalesund opened their new stadium in April 2005, businessman Olav Nils Sunde donated a statue to the club, which was erected in front of the stadium. Whilst Sunde denied it, the statue bore a very strong resemblance to Riise. In 2007, when Riise played in the Champions League Final, a Norwegian commentator demanded the statue officially carry his name. Riise himself has said, "[The name change] is not for me to decide. Everyone sees who it is, and I know that it was made for me."
