Alligator Creek is a rural/residential district generally 20 km south-east of central Townsville.

The creek's headwaters are in the Muntalunga Range (Mount Elliot) about 15 km south. It flows into Cleveland Bay, passing by the site of the former Alligator Creek railway station, and from about that point it forms the western boundary of the coastal part of Bowling Green Bay National Park (55,300 ha). Upstream in the Alligator Creek, in the Mount Elliot part of the National Park, there are pools and cascades. Despite the relatively low rainfall around Townsville, the Range catches enough moisture to support a tropical rain-forest.

Alligator Creek's built-up area is on the railway line and the Bruce Highway. It has a bowls club and a roadhouse/service station. The nearest school is at Stuart.
