The Lockyer Creek is a creek located in South East Queensland, Australia. A tributary of the Brisbane River, the creek is a major drainage system in the Lockyer Valley. Rising on the eastern slopes of the Great Dividing Range, the creek flows generally north-easterly for more than 100 kilometres (62 mi) before it reaches its confluence with the Brisbane River north-northeast of Lowood, and downstream from the Wivenhoe Dam. The creek is named after Edmund Lockyer.
