James Parker Joyce (17 March 1834 – 16 January 1903) was a 19th-century New Zealand politician from Southland. He is regarded as an Independent, as there were no political parties in Parliament at that time. He was born in Southampton, England, and had come to Southland from the goldfields of Ballarat and Bendigo in 1858. He was a journalist and newspaper editor. He represented the electorates of Wallace from 1875 to 1879 when he was defeated, and then Awarua from 1881 to 1887, when he retired. Parker Joyce's great great great grandson is New Zealand filmmaker and rugby player Winston Cowie.
