The R46 is a New York City Subway car model that was built by the Pullman Standard Company from 1975 to 1978 for the IND/BMT B Division. They replaced all remaining R1–9 fleet cars and General Electric-powered R16s, and some R10s. The R46 order initially consisted of 754 single cars, each 75 feet (23 m) long, and was the largest single order of passenger cars in United States railroad history at the point of the fleet's completion. The R46 was the second order of 75-foot cars to be ordered for the New York City Subway, after the R44s.

The first R46s ran in passenger service on July 14, 1975. The fleet was initially slated to be delivered between 1973 and 1975, but a strike at Pullman's factory delayed final deliveries until 1978. Several hundred cracks were found in the R46 trucks during their first few years of service, leading them to be referred to as "the most troubled cars ever purchased". Morrison–Knudsen rebuilt the R46s in 1990–1992. The R211 order is replacing the entire fleet of R46s, and as such are expected to remain in service until the late-2020s.
