The NZR WH class was a class of three steam locomotives built by Manning Wardle in 1884 for service on New Zealand's private Wellington and Manawatu Railway Company (WMR). They did not acquire their WH classification until 1908 when WMR was nationalised and incorporated into the New Zealand Government Railways (NZR). A total of five locomotives were purchased by the WMR but two had been sold by the time NZR took over the company.
