Coat of arms of the London Borough of Bexley is the official coat of arms of the London Borough of Bexley, granted on 20 May 1965. The arms have wavy lines representing the rivers Thames, Cray and Shuttle, on which Bexley is situated. The gold fields at top with the oak tree and bottom with the cog wheel represent the agricultural and mineral wealth of the Borough. The oak tree was taken from the arms of the former Bexley council, and also signified the rural nature of much of the council's area. The red saltire has no official meaning, but it can be noted that there is also a red saltire in the arms of the Diocese of Rochester, to which Bexley belongs.
