The Boothtown Aqueduct is a heritage-listed 19th-century, Victorian Romanesque style water bridge in Greystanes, Sydney, New South Wales, Australia.

Established in 1888, the aqueduct was built to cross a valley to carry water from Prospect Reservoir to residents of Greater Western Sydney.

The tube inlets were built as ornate fortified towers with steel trash racks and sluice gates to control the water flow.

Fairly decorative features are integrated into the brickwork, such as dentilation, pilasters to each arch and string courses of round cast bricks.

[7] Described as having "Roman architecture", the aqueduct was one of the first of its kind to use green technology, as it featured the power of gravity to transport water, before failing rather early after its construction and was finally bypassed altogether, becoming a white elephant (despite being a striking landmark in the landscape when the encompassing area consisted of small farmlands and bush).
