The Gladiator 24 is an American trailerable sailboat that was designed by Bill Lapworth as a racer-cruiser and first built in 1958.

The Gladiator 24 is a development of the Lapworth 24, with a shorter mast and a raised deck.

The design was built by Continental Plastics in Costa Mesa, California, United States, starting in 1958, but is now out of production.

The Gladiator 24 is a recreational keelboat, built predominantly of fiberglass, with wood trim. It has a fractional sloop rig; a spooned, raked stem, a raised counter, angled transom; a keel-mounted rudder controlled by a tiller and a fixed modified long keel, with a cut-away forefoot. It displaces 3,850 lb (1,746 kg) and carries 2,050 lb (930 kg) of ballast.

The boat has a draft of 4.00 ft (1.22 m) with the standard keel.

The boat is normally fitted with a small 3 to 6 hp (2 to 4 kW) outboard motor for docking and maneuvering.

The design has sleeping accommodation for four people, with a double "V"-berth in the bow cabin, a straight settee on the port side of the main cabin and an aft quarter berth on the starboard side. The galley is located on the port side just forward of the companionway ladder and is equipped with an icebox and a sink. The head is located centered under the bow cabin "V"-berth. Cabin headroom is 57 in (140 cm).

For sailing the design may be equipped with either a jib or genoa foresail.
