The M114 is a World War 2 era towed howitzer of US origin. It was developed in the early 1940's and was used in large numbers during World War 2. The original designation was 155mm Howitzer M1, but after World War 2 it was redesignated as the M114.

The M114 uses a two wheel split trail carriage. A single jack in front of the axles raises the wheels from the ground. The 155mm ordnance is derived from the 1917 Schneider, but is longer and features a new breech. The 24-caliber ordnance does not feature a muzzle brake. A gun shields adds a limited degree of protection for the 11 men crew.

The M114 fires M107 range of 155mm NATO standard ammunition. The maximum range is 14.6 km. The maximum rate of fire is 4 rounds per minute. In four minutes 8 rounds can be fired and the sustained rate of fire is 40 rounds in one hour.

The M114 is usually towed by a 5 ton truck, which also transports the crew and ammunition. It is too heavy to be man handled over all but very short distances. Emplacement time is about 5 minutes.

The M114 was used in large quantites by US forces during World War 2. After World War 2 it remained in active use for several decades and was widely used in the Korean War and Vietnam War. Later on it was replaced by the more capable towed M198 and by self-propelled howitzers. The M114 was adopted by many US allies during and after World War 2. In several nations it remains in active use today.
