Londerzeel

Londerzeel won the Belgian Fourth Division twice, in 2006 and again in 2013, both times in Division B, and both titles carried the club up to the Third Division. It came after a decade of upheaval: relegation in 1994, five years in the lower divisions before a return in 1999, then a steady climb through the 2000s that ended with the club's first spell in the Third Division.

The club is Koninklijke Londerzeelse Sportkring, and it began with an odd choice of federation. Founded in 1929, it did not join the Belgian association, as most clubs did, but the Vlaamsche Voetbalbond, a rival Flemish body. It stayed there until 1944, when the Vlaamsche Voetbalbond was dissolved and the club moved over to the Royal Belgian Football Association.

The ground on Brusselsestraat has had three names: Burgemeester Albert Lambertsstadion, Stadion Dirk Putteman and now the Eeckelaers Stadion, which holds 3,000. Red and blue are the colours. The nearest rivalry is local, with Delta Londerzeel, while the fixture that carries a name is the Derby Diegem–Londerzeel, against Diegem Sport.

In 2024–2025 the club plays in Division 2 of the Belgian amateur league. That sits one step below the Third Division level it reached in 2006 and again in 2013.
