Glenlyon Dam, also known as Pike Creek Reservoir, is an earth and rockfill dam in Queensland near the border with New South Wales, roughly between Stanthorpe and Texas to the west.

Glenlyon Dam provides water for irrigation of grain and fodder crops.

In the upper reaches of feeder creeks, there are large areas of standing timber and submerged logs.
