Timo Hildebrand (born 5 April 1979) is a German professional football goalkeeper who plays for Schalke 04. Hildebrand holds a Bundesliga record for keeping a clean sheet for 884 consecutive minutes in 2003–04.

VfB Stuttgart
After starting his career at the little known FV Hofheim/Ried, Hildebrand joined the Stuttgart youth team in 1994.

From the summer of 2000, he was the club's number one goalkeeper and contributed largely to Stuttgart's successes, particularly as part of what became known as "Stuttgart's young wild ones" team under coach Felix Magath who, due to financial restraints, had to rely on young players. Largely thanks to Hildebrand's steady performances, VfB Stuttgart managed to be Bundesliga runners-up in 2003 and survived the Champions League group stage the following season, before bowing out to Chelsea FC in the second round. Hildebrand also played a significant role in Stuttgart's victorious 2006–07 Bundesliga campaign, figuring as a backbone for the next generation of "wild ones" like Serdar Tasci or Mario Gómez and helping Stuttgart provide the third-best defence of the season. The 2006–07 campaign remains his greatest domestic success to this day, and his last season with Stuttgart as in December 2006 he did not accept the club's offer to extend his contract.

Valencia
Hildebrand joined the Spanish club Valencia on a free transfer on 3 July 2007, with Valencia unveiling Hildebrand via a news conference the next day on 4 July 2007. He stated in the news conference that he would "give everything" to the club. Hildebrand was being viewed as a replacement to the club's long-serving goalkeeper Santiago Cañizares. He made his debut for Valencia on 29 August, for the third qualification round second leg of UEFA Champions League against IF Elfsborg. He played the full 90 minutes of that game of which they won 3–0.

Hildebrand was Valencia's first-choice goalkeeper for most part of the 2007–08 season, collecting a Copa del Rey trophy on the way. After Ronald Koeman's departure as Valencia manager, Hildebrand lost his place in the first team as Koeman's successor Unai Emery preferred newly signed Renan Brito instead. According to media coverage, he refused to take place on the bench and was eventually cut from the squad altogether. Hildebrand had not been playing for Valencia for several months since the Supercopa de España second leg on 24 August 2008. On 4 December 2008, he left Valencia by mutual consent.

Hoffenheim
On 10 December 2008, Hildebrand signed for the Bundesliga side 1899 Hoffenheim. He made his Bundesliga debut for Hoffenheim on 31 January 2009 in their 2–0 win at home to Energie Cottbus, being substituted in the 60th minute due to an injury. In summer 2010, Hildebrand left Hoffenheim.

Sporting
Hildebrand signed a one-year deal with Portuguese Sporting CP and debuted on 16 October 2010 in a 2–1 win over GD Estoril Praia in the Portuguese cup. After Hildebrand left Sporting, he was on trial with Manchester City on their pre-season tour of USA before the 2011–12 season, but they did not take up the option to sign him.

Schalke 04
Hildebrand signed onto Schalke 04 in the middle of the 2011–12 Bundesliga campaign after starting keeper Ralf Fährmann was injured.
