The '''O^C class''', built by the [[Baldwin Locomotive Works]] for the [[Wellington and Manawatu Railway]] (WMR) in [[New Zealand]], consists of a solitary [[Locomotive#Steam|steam locomotive]]. Ordered in 1896 as an externally similar but more powerful version of the [[NZR Oa class|O^A class]] locomotive ordered in 1894, it entered service in June 1897 as No. 16. It was a [[Vauclain compound|Vauclain]] [[compound locomotive]].{{sfn|Palmer|Stewart|1965|p=94}}

In 1908, the WMR and its locomotive fleet was purchased by the [[New Zealand Railways Department]] (NZR) and incorporated into the [[Rail transport in New Zealand|national rail network]], and although No. 16 bore a likeness to members of the [[NZR O class|O class]], it was sufficiently different that it warranted separate classification. Technical differences were sufficient that it was not classified with the visually similar WMR No. 13/NZR O^A 457, and it became O^C 458. It is known to have operated on the line from the [[Hutt Valley]] through the [[Rimutaka Range]] to the western end of the [[Rimutaka Incline]], and its final depot was at Cross Creek at the eastern end of the Rimutaka Incline in the [[Wairarapa]]. It was withdrawn from service in July 1930.
