Greenvale Reservoir is an off-stream water storage dam in northern Melbourne, Victoria, Australia. It is situated in the upper Yuroke Creek catchment, the major tributary of the Moonee Ponds Creek. It is in the north of the suburb of Greenvale and to the west of Roxburgh Park.

The reservoir has a capacity of 27,000 ML (950 million cu ft). It was opened 18 April 1973 and is now managed by Melbourne Water. The reservoir was designed to supply drinking water to Melbourne's northern and western suburbs.

The Greenvale Reservoir Park, to the south and west of the dam, contained picnic tables, a playground and barbecues, and is managed by Parks Victoria. The park was closed in 2014, because of the need for work to strengthen the dam wall. Although the remedial work has been completed, most of the park remains closed, despite occasional promises to reopen it. The northern section is open to pedestrian traffic.
