Ranulph Dacre (23 April 1797 – 27 June 1884) was a British master mariner and merchant active in Australia and New Zealand.
[3] He arrived in Australia in August 1823 as master of Elizabeth (363 tons) owned by London merchant Robert Brooks, who was also aboard.
[5] At Tahiti Dacare took aboard the Reverend Daniel Tyerman and George Bennet (missionary) on their famous inspection tour of South Sea missions, and gave them passage to Sydney.
[6] He continued to trade around the region, and made two voyages back to Britain on the Surry, before deciding, in about 1830, to settle in Australia.
His poor record-keeping was another issue that prompted Brooks to replace him as his agent in 1843 with another master mariner, Robert Towns.
Dacre traded successfully with the Māori population of New Zealand, including Eruera Maihi Patuone.
