Stepaside (Irish: An Chéim)[1] is a village in the townland of Kilgobbin, located in south County Dublin, in Dún Laoghaire–Rathdown, Ireland.

Stepaside developed in the 18th and early 19th centuries when the adjacent medieval settlement of Kilgobbin was bypassed by a new stretch of the Enniskerry Road, was built from what is now Lamb's Cross through to Kilternan.

Stepaside became a new staging post along this route, while Kilgobbin Road with its coaching inn (now Oldtown House) was no longer used by goods traffic or stagecoaches.

[2] Previously a separate rural village, as of the early 21st century, Stepaside has been absorbed by the Dublin conurbation to the north and east, and has seen accompanying residential development and population growth.

The Luas Green Line has been extended to Cherrywood and the nearest stops (Glencairn and The Gallops) are approximately 2 kilometres (1.2 mi) from the centre of Stepaside.

[8] It has heritage buildings, garden areas, parkland and woods, located close to Stepaside village (one entrance is opposite the Belarmine development).
