The London Underground 1972 Stock is a type of rolling stock used on the London Underground. The 1972 Stock was originally ordered to make up the shortfall in trains on the Northern line's 1959 Tube Stock fleet. The 1972-tube stock operated on the Bakerloo, Northern, and Jubilee lines. A few trains were later converted for use on the Victoria line. The design was similar to the 1967 Victoria line trains with longer windows, curved cab sides and fluorescent interior lighting. On introduction they had unpainted aluminium bodywork.

The 1972-tube stock was replaced on the Northern and Jubilee lines, but still operates on the Bakerloo line. Following the withdrawal of the British Rail Class 483 EMUs in 2021, the 1972 Stock are now the oldest EMUs in passenger service in the United Kingdom. A total of 63 seven-car trains were built in two separate batches. The class received the Class 499/2 designation on British Rail's TOPS system to operate on the Bakerloo line north of Queens Park.
