SBV Excelsior is a professional football club from the Kralingen-Crooswijk district of Rotterdam, Netherlands. It was founded on July 23, 1902 and was formerly known as 'Rotterdamse Voetbal en Atletiek Vereniging Excelsior' (Rotterdam Football and Athletics Union Excelsior). The club was relegated from the top Dutch league, Eredivisie in 2007/08, and promoted back to the Eredivisie at the end of the 2009/10 season.
Excelsior used to be a satellite club of Feyenoord, where Excelsior received money and players (either on loan or free transfer) from Feyenoord. That system ended in 2005. The agreement was set up again in 2009, which resulted in the loan of several Feyenoord players to Excelsior for the 2009–10 season. Excelsior's home stadium is the Stadion Woudestein, which has a capacity of about 3,531, one of the smallest stadiums hosting professional football in the Netherlands.
The main rival of Excelsior is Sparta, another professional football team from Rotterdam.
