Meda-Therese McKenzie MBE (born 1963), generally known as Meda McKenzie, is a former New Zealand long-distance swimmer, who was inducted into the New Zealand Sports Hall of Fame in 1996.
She also swam Foveaux Strait; and in England the English Channel and a double crossing of the Bristol Channel.
After retiring to raise two children, she returned after five years to swim across Lake Erie in Canada, and two firsts: the first double crossing of Cook Strait by a woman and a circumnavigation of Rarotonga.
In the 1978 Queen's Birthday Honours, McKenzie was appointed a Member of the Order of the British Empire, for being the first New Zealand woman to swim Cook Strait and the first person to swim Cook Strait in both directions.
