The R68 is a type of New York City Subway car. The 425-car contract was a joint venture of Westinghouse AM-Rail Company, ANF Industrie of Paris, and other companies. The cars were built in France from 1986 to 1988 and shipped to New York Harbor. They replaced many R10s, and all remaining R16s.

The R68 was the third R-class contract to be built with 75-foot (23 m) cars, which have more room for sitting and standing passengers per car than the convert|60|ft|m|sing=on cars that were used previously. However, because convert|75|ft|m|sing=on cars take longer to load and unload, and because convert|75|ft|m|sing=on cars cannot fit in the entire B division, more recent orders have returned to convert|60|ft|m|sing=on cars.

The R68's manufacture suffered from significant system integration problems. Inadequate communication and coordination between the carbody builder (ANF Industrie) and the chassis assembler (Westinghouse) led to operational failures; the R68 became known as a lemon. However, extensive work performed by the New York City Transit Authority ultimately provided solutions to the car's many problems, and today the R68 has among the highest Mean Distance Between Failure (MDBF) in the fleet. The R68's first entry to revenue service was on June 20, 1986 on the NYCS service|D service; the first cars were numbered 2500-2507. There were two contracts to supply the R68. The primary order was: 2500-2724, and the R68-1 option order was 2725-2924. The fleet today primarily runs on the NYCS service|B, NYCS service|D, NYCS service|Q, Franklin Avenue Shuttle, and NYCS service|W with several sets on the NYCS service|N. R68s are based out of the Concourse Yard in the Bronx and the Coney Island Complex in Brooklyn.
