Cotton Tree is a coastal neighbourhood within the suburb of Maroochydore in the Sunshine Coast Region, Queensland, Australia.

This was established after Andrew Petrie explored the area in 1838 and named the Maroochy River using the language of Brisbane aboriginals who accompanied him.

The town of Maroochydore was subdivided from the Cotton Tree reserve in 1903 by Surveyor Thomas O'Connor.

The land size changes significantly based on the sand movement and development of river mouth.

Surf breaks include Pipes/Seabreeze, Poofters dunnies/Abdul's, Carpark, Pinnies, the Mouth and North Shore.

(Pipes was named after the location of the old sewer effluent pipe, Poofters after a derelict toilet block, Abdul's after death of local surfer Ryan Abdy) Although 'unbounded' as a suburb it's generally recognised as being east of Aerodrome Road and including all numbered avenues and esplanades.
