Warialda is a town in the North West Slopes region of New South Wales, Australia, in Gwydir Shire.

Agriculture, health and education are the primary industries providing support for a small but thriving business sector.

The Anglican and Catholic churches are located near the Gwydir Highway in the main part of town on the south bank of the Warialda Creek.

St. Simon's & St. Jude's Anglican Church is located on the corner of Stewart Avenue and Market Streets.

The front of the church has three stained glass windows representing The Good Shepherd, from John 10:1–21, as an Australian scene.

The Presbyterian Manse was built from convict-hewn sandstone which formed part of the original town gaol.

The Manse bears examples of gaol graffiti, such as "Hell is here" upside-down outside the office window, and "Lord, remember me" at the back of the building.

Noel Cleal and his brother Les emerged from the town to rise to prominence with Eastern Suburbs in the New South Wales Rugby League premiership, with Les later going on to captain-coach many country club sides while Noel won a title with Manly Warringah in 1987.

The highlight of the day happens at 2pm when there is a street parade with colourful floats constructed and manned by community groups.
