Sheldon is a rural/residential suburb of Redland City between Capalaba and Mount Cotton, 22 km south-east of central Brisbane. It was formally named in 1980. 'Sheldon' is an old English (Derbyshire) expression describing steep hills or a wooded valley.
The Tingalpa Creek flows from Mount Cotton through Sheldon to the Leslie Harrison dam/Tingalpa reservoir (1968), part of Redland City's water supply. Much of Sheldon serves as a catchment for the water. The resulting bushland areas join the Koala Bushlands in Burbank.
Sheldon College (1997) is a non-denominational K-12 school, a short distance outside Capalaba. Nearby in Duncan Road, the border between Sheldon and Capalaba, there is the council's Sheldon Tennis Centre.
