Waasland-Beveren Sinaai Girls is a Belgian women's football club from Klein-Sinaai, Sint-Niklaas.

[1] Founded in 1988, Sinaai Girls has played in the Belgian First Division since 1994.

Sinaai Girls has been most successful in the Belgian Cup with three titles in a row between 2009 and 2011, the first 3-year winning streak in the competition since 1979.

Since 2007 the team has ended in the First Division's top five positions, with 2010's 3rd spot being its best historic result.

[3] When it became apparent that it was almost impossible for an autonomous women's football club to continue to compete at the highest level (BeNe League / Super League), a conscious decision was made in 2014 to return to the Wijnveld stadion and to play on a lower level.
