St Julians (Welsh: Sain Silian) is a community and coterminous electoral district (ward) of the City of Newport, South Wales.

The development is however controversial as it is situated on a former 1930s and 1960s industrial site[4] at the Glebelands in the western part of St Julians.

[citation needed] St Julians is also the name of the coterminous electoral ward to Newport City Council.

It was owned and lived in by the Herbert family until about 1720 when the Tudor mansion was downsized to a farmhouse and parts of the estate became derelict.

The land surrounding the house had by this point been sold off and built on, leaving St. Julian's to become completely derelict by the 1970s.
