The MacGregor 25 is an American trailerable sailboat that was first built in 1973. From the start of production until 1980, it was sold as the Venture 25.

The boat was built by MacGregor Yacht Corporation in the United States between 1973 and 1987, but it is now out of production. During its 14-year production run 7,000 examples were completed.

Designed by Roger MacGregor, the MacGregor 25 is a small recreational keelboat, built predominantly of fiberglass, with wood trim. It has a fractional sloop masthead sloop rig, a transom-hung rudder and a fixed stub keel with a centerboard. It displaces 2,100 lb (953 kg) and carries 625 lb (283 kg) of ballast.

Starting in 1980, a number of boats were built with a masthead sloop rig and known as the MacGregor 25 MH.

The boat has a draft of 5.67 ft (1.73 m) with the centreboard extended and 1.50 ft (0.46 m) with it retracted, allowing beaching or ground transportation on a trailer.

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

The design has sleeping accommodation for five people, with a double "V"-berth in the bow cabin, a straight settee in the main cabin on the port side and drop-down dinette table on the starboard side that forms a double berth. The galley is located on the port side just forward of the companionway ladder. The galley is equipped with a two-burner stove and a sink. The head is located just aft of the bow cabin on the starboard side. Cabin headroom is 57 in (145 cm).

The masthead rigged version has a PHRF racing average handicap of 231, with a high of 246 and low of 222. All models have a hull speed of 6.43 kn (11.91 km/h).
