Gjerdrum was established as a municipality on 1 January 1838 (see formannskapsdistrikt).
The municipality (originally the parish) is named after the old Gjerdrum farm (Norse Gerðarvin). The first element is the genitive of a river name Gerð and the last element is vin f 'meadow, pasture'. The river name is derived from the Norse word garðr meaning 'fence' and so the meaning is 'the river whose function is a fence (and/or as a border)'.
The coat-of-arms is from modern times. They were granted in 1993. The arms show a traditional Norwegian form of roundpole fence. The arms are also canting because the name of the municipality refers to a fence.
The local sports team is Gjerdrum IL.
