The coat of arms of Adelaide was granted by the Heralds' College on 20 April 1929.

Above the shield is a golden mural crown, [1] which is a common element in the arms of municipalities.

It is a right arm holding a miner’s pick, representing another of the industries of the early years which contributed so much to the wealth of South Australia and Adelaide.

The base of the shield stands on a grassy green field of rising ground.

A scroll below the arms has a Latin motto Ut Prosint Omnibus Conjuncti which translates as "united for the common good".
