Gingin is a town in Western Australia, located on the Brand Highway 67 kilometres (42 mi) north of the Perth city centre.

The town's economy is mostly based on its agriculture, although there has been an increasing focus on science with the establishment of the Australian International Gravitational Observatory and Gravity Discovery Centre.

The first European to visit the area was the explorer George Fletcher Moore; he arrived in 1836 and recorded the Aboriginal name "Jinjin" on his charts.

In 2003, plans were unveiled to construct the Gravity Discovery Centre near Gingin adjacent to the existing Australian International Gravitational Observatory.

– The Gravity Discovery Centre includes a 45 m tower that leans at an angle of 15 degrees that allows students to complete free fall experiments.
