The New Zealand DM/D class electric multiple unit^[a] (also known as English Electrics) were a type of electric multiple units used on the suburban rail network of Wellington, New Zealand. Formed of DM power cars and D trailer cars, the first units were ordered from English Electric in 1936 and introduced on 2 July 1938 operating the electrified Johnsonville Line service. Additional units were ordered in 1942 for the line, and in 1946 as the other Wellington suburban lines were to be electrified.

The units were relegated to peak services and the Johnsonville Line after the arrival of the "Ganz-Mavag" EM/ET units in 1982–83, before finally being replaced by the "Matangi" FP/FT units in 2011–12. The units operated their last revenue service on 25 June 2012, from Wellington to Melling and return. Five complete units (four two-car and one three-car) and six trailer cars have been preserved.
