The NZR E class of Double Fairlie steam locomotives were two different types of Fairlie steam locomotives, used on New Zealand's railway network.

They were the first classes to take that designation, followed by the E class Mallet compound locomotive of 1906 and then the E class battery electric locomotive of 1922. The other Double Fairlie class was the B class, and there were also the Single Fairlie R and S classes.
