For other uses, see Hewitt (disambiguation).

A Hewitt is a hill in England, Wales or Ireland over two thousand feet (609.6 m) high with a relative height of at least 30 m. The list was compiled and is maintained by Alan Dawson.

There are 525 Hewitts in total: 178 in England, 137 in Wales and 211 in Ireland (Black Mountain is in both England and Wales). Scotland is not included because it has so many mountains; instead there are separate lists called Munros, Corbetts, Donalds, and Grahams.

Some hillwalkers attempt to climb all the Hewitts; this is a form of peak bagging.
