The Conway class sailing sixth rates were a series of ten Royal Navy post ships built to an 1812 design by Sir William Rule. All ten were ordered on 18 January 1812, and nine of these were launched during 1814, at the end of the Napoleonic War; the last (Tees) was delayed and was launched in 1817.

These ships were originally designated as "sloops", but were nominally rated as sixth rates of 20 guns when built, as their 12-pounder carronades were not included in the official rating. When this changed in February 1817, they were rated at 28 guns.
