The AMF 2100 is an American trailerable sailboat that was designed by Ted Hood as a cruiser-racer and first built in 1980. The design's designation indicates its approximate length in hundredths of a foot.

The design was built by the Alcort division of AMF, Inc. in the United States, between 1980 and 1983, but it is now out of production.

The boat did not sell in large numbers as it was competing with the J/24, which had been introduced three years ahead of the AMF design.

The AMF 2100 is a recreational keelboat, built predominantly of fiberglass, with wood trim. It has a fractional sloop rig, a raked stem, a plumb transom, a transom-hung rudder controlled by a tiller and a lifting keel. It displaces 2,200 lb (998 kg) and carries 850 lb (386 kg) of lead keel ballast. The keel is lifted with a winch located in the cabin. The design has positive flotation and is unsinkable.

The boat has a draft of 4.00 ft (1.22 m) with the centerboard extended and 1.00 ft (0.30 m) with it retracted, allowing beaching or ground transportation on a trailer.

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 two straight settees in the main cabin. Galley provisions include an optional portable stove, sink and cooler. The head is located in the bow, just forward of the keel trunk and partitioned from the main cabin by a curtain. Cabin headroom is 51 in (130 cm).

The design has a PHRF racing average handicap of 228 and a hull speed of 5.6 kn (10.4 km/h).
