John Geddie (1815-1872) was a Scots-Canadian missionary who was known as "the father of Presbyterian missions in the South Seas." He pioneered missionary work in the New Bebrides islands, now known as Vanuatu. He became Doctor of Divinity in 1866. He died in Geelong, Australia.

Geddie Memorial Church in Springbrook on P.E.I.’s north shore, has historical value - not only for its age and architectural style, but for its associations with the Presbyterian church and Rev. John Geddie. A Presbyterian congregation was established in the Springbrook area in 1810. Geddie Memorial Church was built in 1836-1837 by James Clark assisted by local carpenters. This church replaced an earlier log structure which was constructed at nearby Yankee Hill by Rev. John Keir. The land for the church was provided by the Anderson family, early Scottish settlers in the area, and the church was first known as Anderson's Church. The church was later renamed in honour of Scottish-born, Nova Scotia raised, Rev. John Geddie (1815-1872) who was ordained and inducted into the pastoral charge of Cavendish and New London at Geddie Memorial Church in March 1838. Rev. Geddie continued to serve the charge until 1845 when he resigned to travel to Aneiteum, New Hebrides, where he and his family conducted missionary work for over twenty years. Several artifacts pertaining to Geddie are displayed in the church.
