Haverhill is an industrial market town in the county of Suffolk, England, next to the borders with Essex and Cambridgeshire. It lies approximately eighteen miles southeast of Cambridge and sixty miles north of London. It is the second town of the borough of St Edmundsbury, and has a population of around 22,000. It is pronounced 'Hay-ver-il'.

Haverhill's economy is dominated by industry, and a large industrial area on the southern side of the town is home to a large number of manufacturing companies such as Wisdom toothbrushes, Gurteen clothing, Winmau Dartboards, and Grampian Foods (in Little Wratting near Haverhill). Other companies deal in chemicals (International Flavours & Fragrances), waste processing, transport and construction. More recently, a cutting edge biotechnology firm - Genzyme has also moved in.

In November 2004, Haverhill achieved an alleged world first, becoming the only known town to feature a laser-lit sculpture on a roundabout. The steel sculpture, called Spirit of Enterprise, dominates the main gateway roundabout on the road from Cambridge, and has caused controversy among local people.

A weekly market is held in the town in the High Street, this has been a long running tradition throughout Haverhill's history (as is also the case for many other market towns in England).
