Sven Andersson (born 6 October 1963) is a retired Swedish football goalkeeper. Born in Strömstad near the Norwegian border, he began his professional career in Örgryte IS, a club with which he won the Allsvenskan championship in 1985. He got 1 cap for Sweden, and was called up as a reserve in the Swedish squad for the 1990 FIFA World Cup in Italy.
In 1993, after having retired from professional football, he was persuaded by Helsingborgs IF to make his comeback. Between 1993 and 2001 he played 233 consecutive Allsvenskan matches, and a total of 268 matches for the club. He was suspended from what was planned to be his last match for HIF due to a red card in his 233rd match.
In 2000, he earned his nickname San Siro-Sven with a last-minute penalty save against Inter Milan. In a 2000-01 UEFA Champions League qualifier, Helsingborgs were leading 1-0 on aggregate from the first leg with the second leg delicately poised at 0-0. In the final minute Inter were awarded a penalty but Alvaro Recoba saw his effort saved by Andersson, and Helsingborgs qualified at Inter's expense.
In November 2001 he joined Premier League side West Ham United, but left the following summer having not made an appearance for the club.
Today Sven Andersson is the goalkeepers' coach of IFK Göteborg.
