The J/24 is a one-design racing keelboat and the first J/Boats product. It achieved global success, with more than 5,200 built, though it is now out of production. It is recognised by World Sailing and supports active competitive fleets and championships worldwide, including the J/24 World Championship.

The first J/24 was built in 1976 by then amateur designer Rodney Johnstone. At a time when sailing was dominated by the International Offshore Rule, the boat was designed to compete under a variety of handicaps, including the MORC. It was immediately successful in racing. Rodney partnered with his brother Bob (then a marketing vice-president at AMF) to form J/Boats. Tillotson-Pearson put the boat into production. With a low price, astute marketing, and heavy promotion, 1,200 were sold in the first two years.

Since then it has been produced by a number of licensed builders, all tightly controlled by the class association and J-Boats.
