Fixby is a suburb in north-west Kirklees bordering neighbouring Calderdale and is traditionally part of Huddersfield in the English county of West Yorkshire. Fixby is mentioned in the Domesday Book.
In the nineteenth century Fixby was a large estate to which social reformer Richard Oastler was appointed as steward from 1830 until 1838 when he was relieved of his duties for his political activities: pamphleteering, lobbying and in the establishment of Short Time Committees in industrial towns throughout Yorkshire. The Short Time committees organised public meetings in order to raise petitions to improve conditions for children in the workplaces of the day and resulted in the Factory Act of 1847, with which Oastler was never fully satisfied.
Much of the historical Fixby Estate is now a golf course, based at Fixby Hall and intersected by the Kirklees Way footpath.
Fixby is often now recognised as the most affluent area of Huddersfield and is home to numerous millionaires.
The area is home to a large shop which is part of the Nisa supermarket chain. The Huddersfield Crematorium is also situated in the area.
The area has a few notable public houses. The Shepherds Arms was run by former Rugby League player Billy Pickup with his wife Sharon and The Clough House. The previous Ash Brow is now an Indian restaurant. The Shepherds is now shut.
