The R27 was a New York City Subway car model built by the St. Louis Car Company from 1960 to 1961 for the IND/BMT B Division. A total of 230 cars were built, arranged in married pairs. Two versions were manufactured: Westinghouse (WH)-powered cars and General Electric (GE)-powered cars.

The first R27s entered service on November 15, 1960. In early 1989, twenty-seven R27s were rebuilt and painted in the fox red paint scheme that also appeared on the R30s, with the intention to operate these cars for several more years. The unrebuilt R27s were replaced by the R68As, with the last unrebuilt train running on May 12, 1989. Almost all overhauled R27s were retired the same year due to reliability problems and the lack of air conditioning on the cars. The R27 cars were retired in the early 1990s; none of the R27 fleet were preserved, since they were identical to the later R30/R30A fleet.
