Little Chalfont Farmers' Market serves Amersham, Chalfont St Giles, Chorleywood, Chesham and the surrounding villages. It is part of the Thames Valley Farmers' Market Cooperative which has markets all over Berkshire, Buckinghamshire and Oxfordshire.

The co-operative exists to manage and promote Farmers' Markets, enabling farmers and small producers to sell their produce directly to the customer. It began operating in 1999 and now flourishes in 14 towns.

Buying at farmers' markets helps to support local farmers and producers. There are no middlemen involved, and no profits for supermarkets and their shareholders. The funds raised through membership fees and stall fees are ploughed back into the co-operative. All producers are voting members who can share in the way the co-operative is run.

Little Chalfont Farmers Market was launched in September 2009, with the support of the Parish Council and local regeneration groups. They wanted to see local produce brought into the heart of the village and give the community an opportunity to come together, to browse, to shop, to meet friends and see what Little Chalfont has to offer.
