The Board of Ordnance in the Kingdom of Ireland (1542–1800) performed the equivalent duties of the British Board of Ordnance: supplying arms and munitions, overseeing the Royal Irish Artillery and the Irish Engineers, and maintaining the fortifications in the island.

The Board of Ordnance was a British government body. Established in the Tudor period, it had its headquarters in the Tower of London. Its primary responsibilities were 'to act as custodian of the lands, depots and forts required for the defence of the realm and its overseas possessions, and as the supplier of munitions and equipment to both the Army and the Navy'. The Board also maintained and directed the Artillery and Engineer corps, which it founded in the 18th century. By the 19th century, the Board of Ordnance was second in size only to HM Treasury among government departments. The Board lasted until 1855, at which point it was disbanded.
