The Sideling Creek Dam is an earth-fill embankment dam with an un-gated spillway across the Sideling Creek that is located in the South East region of Queensland, Australia. The main purposes of the dam are for potable water supply of the Moreton Bay region and for recreation. The impounded reservoir is called Lake Kurwongbah.

The dam is located 2 kilometres (1.2 mi) east of North Pine Dam and 4 kilometres (2.5 mi) northwest of Petrie. The primary inflow is Sideling Creek, a tributary of the North Pine River. To the east of the dam is the Lakeside Park motor racing circuit.

Completed in 1958, the earthfill dam structure is 23 metres (75 ft) high and 500 metres (1,600 ft) long. The 280-thousand-cubic-metre (9.9×10^⁶ cu ft) dam wall holds back the 14,500-megalitre (3.2×10⁹ imp gal; 3.8×10⁹ US gal) reservoir when at full capacity. From a catchment area of 53 square kilometres (20 sq mi) that includes the localities of Petrie, Kallangur and Dakabin, the dam creates Lake Kurwongbah, with a surface area of 320 hectares (790 acres). The uncontrolled un-gated spillway has a discharge capacity of 710 cubic metres per second (25,000 cu ft/s). The dam is now managed by Seqwater.
