Barnfield is a suburb of Luton, in the Luton district, in the ceremonial county of Bedfordshire, England. The area is roughly bounded by Old Bedford Road/Cromer Way roundabout to the north; Wardown Park and Wardown Crescent to the south; the A6 to the west; and Old Bedford Road, Elmwood Crescent and Wardown Crescent to the east.
The area is home to Barnfield College, a vocational college, and Luton Sixth Form College, a sixth form. The area consists largely of mature semi-detached and detached houses located around Old Bedford Road.
The area itself is mainly built up residential space, but the River Lea runs through it and there is a green space surrounding the path of the river.
Barnfield is part of the larger Barnfield ward, which also includes Bushmead. The ward is represented by Cllr David Franks (Liberal Democrats) and Cllr Amjid Ali (Liberal Democrats).[2] The ward forms part of the parliamentary constituency of Luton North, and the MP is Sarah Owen (Labour).
Two weekly newspapers cover Barnfield, although they are not specific to the area.
