St Martins Tower is a 140-metre office building in Perth, Western Australia, with 33 floors. Its top floor with windows, level 33, holds C Restaurant, a revolving restaurant that turns to give diners a changing view over the city. The building was the tallest in Perth from its completion in 1978 until 1988.

The tower was completed in 1978 and held the title of Perth's tallest building for about a decade until 1988. It was built during a period of strong economic growth in Western Australia, when demand for office space in the city center was rising fast.

St Martins Tower sits at the heart of Perth's central business district and is easy to spot from street level. The building serves as a reference point for people moving through the city center on foot.

The tower is located in central Perth and is easy to reach on foot from nearby public transport stops. The surrounding streets have a range of cafes, shops, and services that make the area convenient to explore.

C Restaurant, on level 33, is the only revolving restaurant in Western Australia; that floor is the last one with windows. The tower was long known informally as the AAPT Tower and later as the Amcom building.
