The R44 is a New York City Subway car model built from 1971 to 1973 by the St. Louis Car Company in St. Louis, Missouri for the IND/BMT B Division and the Staten Island Railway. The cars replaced many R1-R9 series cars and all 1925 Standard Steel built SIRTOA ME-1 trains, providing Staten Island with a new fleet of railcars. Currently, only the Staten Island Railway operates this model, as the NYCTA cars were retired in 2010 due to various issues.

A total of 352 R44 cars were ordered: 300 cars for the New York City Subway (numbered 100–399, with 278 of the cars later renumbered 5202–5479) and 52 cars for the Staten Island Railway (also known as ME-2 or MUE-2 cars, numbered 400–435 and even numbers between 436–466).

The R44s originally came in singles, but needed each other to run, much like the "married pairs" of the R26/27/28/30/32/36/36WF/38/40/40A/42 cars. The NYCTA cars were reassembled after overhaul into ABBA sets of four; A cars are evenly numbered with operator cabs while B cars have odd numbers and no cabs. The SIR cars were never reassembled and remain set up as singles.
