Wellington Valley Mission was a Church Missionary Society (CMS) mission in Wellington Valley, New South Wales and one of the earliest to "Civilize and Christianize" Aboriginal people in Australia. It was founded in 1830 and closed 12 years later in 1842. The CMS established the mission in 1832 with Rev. William Watson and Rev. Johann Simon Christian Handt as the missionaries. They were granted acres ( km2) and ₤500 per annum to run the mission. The mission was closed in 1842 after ten years of difficulty and little success.
