Tennis Club Odense is a Danish sporting club in Odense, Denmark. Founded in 1889 as part of Odense Boldklub, Tennis Club Odense is the oldest tennis club on the Danish island Funen. In 1996, the club withdrew from Odense Boldklub and founded the independent tennis club, operating under its current name since 2007.
Tennis Club Odense is a member of Funen Tennis Association (FTU) and the Danish Tennis Association (DTF), the governing bodies of Funen and Danish lawn tennis, respectively. It has 13 outdoor courts (12 of which are clay courts), but despite being the largest tennis club in Denmark's third largest city, it has had no permanent indoor courts since 2004. Since 2007, however, members of Tennis Club Odense have played indoor tennis in the club's temporary facilities in a local warehouse. Nonetheless, the local authorities have promised building six indoor courts before 2014.
Internationally, the club has hosted the annual ITF Junior Outdoor Cup Odense since 2010, and throughout the 1990s, the club also hosted Funen Open, a major tournament on the ITF Men's Circuit. In 2008, Tennis Club Odense played a major role in organizing of the 2008 Nordea Danish Open – the forerunner for the annual Danish WTA tournament in Copenhagen, Denmark.
Despite being born in Odense, the former world no. 1 on the WTA Tour, Caroline Wozniacki, has never played for or in Tennis Club Odense. Nevertheless, the most successful Danish male tennis player of the 2000s, Kristian Pless, started his career in the club. On a national level, Tennis Club Odense is one of the most successful Danish tennis clubs, winning the bronze medal at the Danish Team Championship in 2009.
