The Qatar and Dubai Currency Board was a short-lived joint monetary authority, established in 1960 after Qatar left the Gulf rupee zone and Dubai — then still a separate British-protected sheikhdom — opted to participate rather than go it alone. The arrangement was unusual: two distinct territories sharing a single currency board and note series, despite having no formal political union. Bradbury Wilkinson printed the full series at their New Malden works, which handled much of Britain's overseas colonial and protectorate currency work through this period.

The board dissolved in 1973 when Qatar established its own central bank and currency. Dubai, by then part of the UAE, followed the dirham. Surviving notes from this series carry the weight of an administrative arrangement that lasted barely a decade.
