Reach is a small village and civil parish on the edge of the fenland in East Cambridgeshire, England at the north end of Devil's Dyke, about 1.5 miles (2.4 km) west of Burwell.

Goods were loaded at its common hythe (wharf) for transport into the fen waterway system from at least 1100.

In medieval times, Reach was a hamlet sitting on the border of the parishes of Burwell and Swaffham Prior.

Reach Fair was historically a grand regional occasion, hosting feasting and parades over three days.

A custom in the fair is for the mayor and other councillors to throw pennies into the crowd for the young people.
