The M29 class comprised five monitors of the Royal Navy, all built and launched during 1915.

The ships of this class were ordered in March, 1915, as part of the Emergency War Programme of ship construction. The contract for construction was granted to Harland & Wolff, Belfast, who sub-contracted the construction of the M29 and M31 to Workman, Clark and Company.

The main armament of the ships, two 6-inch Mk XII guns, came from guns originally intended for the five Queen Elizabeth-class battleships which became surplus when their aft casemate mountings turned out to be unworkable and were dispensed with.
