Saint-Nicolas-du-Pélem (French pronunciation: [sɛ̃ nikɔla dy pelɛm]; Breton: Sant-Nikolaz-ar-Pelem) is a commune in the Côtes-d'Armor department of Brittany in northwestern France.

A large plateau surrounded by an artificial moat near Pélinec pond is sometimes considered to be the remains of a pre-Roman fortification of the Gauls,[5] or of a Roman camp, and sometimes as the remains of a medieval camp (Frotier de la Messelière reports having seen foundations for a circular stone tower).

[6] During the German occupation, the a group of maquis of the FTP operating in the Côtes-du-Nord, was organized during the spring of 1943 in the rectangular area of Trémargat, Lanrivain, Peumerit-Quintin, and Saint-Nicolas-du-Pélem, led by Louis Pichouron, whose nom de guerre was "Commandant Alain".

On 11 November 1943 Théodore Le Nénan killed a member of the Feldgendarmerie in Plouaret; on 23 December Georges Ollitrault attacked a German officer at Loudéac.

An attack on the town hall of Saint-Nicodème resulted in the arrest of many members of the group at Trébrivan, and four were shot on 6 May 1944 at Ploufragan.
