HMS Aldborough was a 20-gun sixth-rate ship of the Royal Navy, built in 1727 according to the 1719 Establishment and in service in the West Indies, the North Sea and the Mediterranean until 1742.

Aboard as passengers for this voyage were James Oglethorpe, the founder of the colony of Georgia, and a delegation of Yamacraw sent to meet with the British Government.

[2] Temporarily restored to seaworthiness, Aldborough was assigned to the command of Captain Nicholas Robinson and transferred to coastal patrol in the English Channel and North Sea.

In 1738 this designation was reversed, with Aldborough restored to the Navy lists as a 20-gun sixth rate and assigned to Mediterranean service under Captain George Pocock.

[6] Aldborough was broken up at Deptford Dockyard on 31 March 1742, in accordance with Admiralty orders that another ship of the same name be constructed in her place.
