Stewart Creek Valley is a rural locality in the Shire of Douglas, Queensland, Australia. In the , Stewart Creek Valley had a population of 24 people.
The locality is bounded to the north by the Daintree River. Stewart Creek rises in Dedin to the south-west and enters the locality from the south and then flows north through the locality becoming a tributary of the Daintree River at the locality's northern boundary.
Stewart Creek Road commences at the western end of the neighbouring town of Daintree and enters the locality from the north-east and loosely follows Stewart Creek, mostly to the east of the creek.
The land use is predominantly grazing on native vegetation with small amounts of crop growing and rural residential housing.
In 1879, John, Archie and Gavin Stewart were the first settlers in the Daintree area.
Twyford Provisional School opened in 1938, noting that the name Stewart's Creek State School was already in use for a school in Stewart's Creek (now called Stuart) in Townsville . The school name being different to the locality name led to a proposal that the locality be renamed Twyford, as mail sent to Stewart's Creek was often wrongly delivered to the Stewart's Creek Gaol in Townsville, leading to delays, but the locality name was not changed. The school closed at the start of 1942 due to low student numbers.
In 1952, the Twyford telephone exchange was installed. In 1953, a new post office was built.
