Original Trepo football shirt De Treffers 00s

De Treffers is an amateur football club from Groesbeek, Netherlands. The club plays in the Tweede Divisie, the highest amateur league of Dutch football.

It was founded in 1919, and its first chairman was Jan Piepenbreier. De Treffers has been a member of the Royal Dutch Football Association since around 1930. In the seasons 1935–1936 and 1936–1937 it was champion of the eastern district of the Eerste Klasse (First amateur league), at the time the highest league in Dutch amateur football. In both seasons De Treffers failed to win the national amateur championship.

After the Second World War De Treffers performed less well. In the 1961–1962 season De Treffers was promoted from Derde Klasse (Third amateur league) to Tweede Klasse (Second amateur league). From 1963 to 1974, with the exception of the 1971–1972 season, De Treffers played in the Eerste Klasse (First amateur league).

From 1974 to 2010, De Treffers participated in the Sunday Hoofdklasse. De Treffers were the only team to play so constantly in the Hoofdklasse during these years. The football club has won the district championship of the Hoofdklasse six times (in 1986, 1988, 1990, 1991, 1998, and 2005). In 1988, 1991, and 1998 De Treffers also won the Sunday amateur championships, and in 1991 and 1998 De Treffers became champion of Dutch amateur football in general.

In 2010 it was promoted to the newly formed Topklasse, the highest amateur league. De Treffers has since qualified for the Tweede Divisie which, since 2016, has succeeded Topklasse as the highest amateur division in the Netherlands.
