Plumelec (French pronunciation: [plymlɛk], Breton: Pluveleg) is a commune in the Morbihan department of the Brittany region, in north-western France.

[citation needed] The commune is situated on the Brittany peninsula and is approximately 10 kilometres (6.2 mi) from the southern coast.

During World War II, on the night of 5–6 June 1944, the SAS team captain Pierre Marienne (9 Free French), responsible for the preparation of Operation Dingson, was accidentally parachuted near Plumelec, 800 metres (2,600 ft) from the la Grée Mill, where there was a German observation post.

In all, there were 42 men from Plumelec and one woman (Ms. Armande Morizur, 35 years), engaged in the Resistance, who gave their lives for the Liberation.

Many cycling races pass through or arrive by the Côte de Cadoudal [fr], which presents a mean slope of 6.2% at Plumelec and a vertical ascent of 43–154 metres (141–505 ft) over 1.8 kilometres (1.1 mi).
