Koonibba is an Aboriginal community in South Australia, west of Ceduna.
Koonibba was formerly an Aboriginal mission, founded in 1901. It was established by the Lutheran Church. In 1914, the Koonibba Children's Home was opened there. The main Aboriginal groups who lived on the mission were Wirangu, Mirning, and Kokatha.
In 1963, the mission was taken over by the South Australian Government, and then in 1975 it was transferred to the Aboriginal Land Trust, which leases the site to a local Aboriginal community organisation, the Koonibba Aboriginal Community Council, Inc., which manages the community.
Today, Koonibba has a population of about 142. It has a public school, the Koonibba Aboriginal School, and a football club, the Koonibba Football Club, which was formed in 1906.
The Our Redeemer Lutheran Church from the former Koonibba Lutheran Mission survives and is listed on the South Australian Heritage Register.
