was an English association football club from Sidcup, Kent which folded in 1915.

The club was instantly a power in the amateur game, one of its earliest competitive matches being a 16–0 win over Woking in the 1905–06 FA Cup qualifying rounds.

Woking only started with 9 men, and, although a tenth soon joined, for the second half the club secretary (E. T. Engall) had to take the field and played in goal.

[5] The club played at Sidcup College,[6] whose ground facilities were so meagre that Plymouth Argyle, when drawn to play there in the FA Cup first round in 1906, offered money to switch the tie to Home Park, and protested to the Football Association when the Crusaders turned the money down.
