The British Rail Class 33 also known as the BRCW Type 3 or Crompton is a class of Bo-Bo diesel locomotives ordered in 1957 and built for the Southern Region of British Railways between 1959 and 1963.

A total of 98 class 33s were built by the Birmingham Railway Carriage and Wagon Company, and they were called "Cromptons" after the Crompton Parkinson electrical equipment installed in them. Like their lower-powered BRCW sisters (BR classes 26 and 27) their bodywork and cab ends were of all steel construction

The original (1957) number sequence was D6500–D6597.
