Euston Square is a large square in the London Borough of Camden in Central London. It lies on Euston Road, and Euston railway station and Euston bus station are on its northernmost side. Although “Euston Square” strictly refers to the square, in day to day use the name is often used to refer to Euston Square tube station, whose entrance is at the junction of Euston Road and North Gower Street. The southern half of the square was built over in the 1920s, leaving Euston Square Gardens on the north side in front of Euston station.
