Alles Door Oefening Den Haag, commonly known by the abbreviated name ADO Den Haag, is a Dutch association football club from the city of The Hague. They play in the Eerste Divisie, the second tier of Dutch football, following relegation from the Eredivisie in the 2020–21 season. The club was for a time known as FC Den Haag, with ADO representing the amateur branch of the club. Despite being from one of the traditional three large Dutch cities, it has not been able to match Ajax, Feyenoord or PSV in terms of success in the Eredivisie or in European competition. There is nonetheless a big rivalry with Ajax and Feyenoord. The Dutch words "Alles Door Oefening" translate into Everything Through Practice.
