Roman Weidenfeller (born 6 August 1980) is a German footballer who plays for Fußball-Bundesliga club Borussia Dortmund as a goalkeeper.

Early career
During his youth years, he played for Sportfreunde Eisbachtal. Weidenfeller then made his professional debut in 1997, after his performances at the 1997 FIFA U-17 World Championship.

Kaiserslautern
In 1998, Weidenfeller transferred to the 1. FC Kaiserslautern youth team where he made 40 appearances in two seasons. He was then promoted to the first team but made only six league appearances in two seasons.

Borussia Dortmund
Weidenfeller moved to Borussia Dortmund in 2002 on a free transfer as a possible replacement for Jens Lehmann, who moved to Arsenal in 2003. Weidenfeller had reportedly been unhappy at Kaiserslautern, where he was used mainly as a backup to Georg Koch. His debut for Dortmund came on 17 December 2003 against his former club, Kaiserslautern, in a 1–0 loss.

In 2005, Weidenfeller underwent surgery following a meniscus tear in his left knee during training.

Early in the 2007–08 season, Weidenfeller was given a three match ban and fined €10,000 for insults leveled against Schalke 04 striker Gerald Asamoah. Asamoah originally reported Weidenfeller after a match on 18 August 2007 between the two clubs, where the incident occurred after a clash between the two in the 51st minute. Weidenfeller offered an apology to Asamoah following the news reports but denied making the statement.
