John (or Johan) Frederick Henry Wohlers (originally Johann Friedrich Heinrich Wohlers, 1 October 1811 – 7 May 1885) was a Lutheran missionary from Germany who lived for 41 years on Ruapuke Island, a small island in New Zealand's far south. Wohlers was born in the North German hamlet of Mahlensdorf, near Bremen, to Johann Gerd Wohlers and his wife Margarethe (née Ahlers). He went to a mission school, and was then sent by the North German Missionary Society to New Zealand, where the New Zealand Company was establishing new settlements.
