Warden Hill is a suburb of Luton, about 3 miles (4.8 km) north of the town centre, in Bedfordshire, England.

Formerly part of the parish of Streatley, Warden Hill was a small hamlet centred on the junction of Icknield Way and the A6 until the 1960s.

Neighbouring areas of Warden Hill are Bramingham to the west, and Bushmead and Runfold to the south.

The Icknield Way Path passes through the hills on its 110-mile (180 km) route from Ivinghoe Beacon in Buckinghamshire to Knettishall Heath in Suffolk.

The wards form part of the parliamentary constituency of Luton North and the MP is Sarah Owen (Labour).
