Noyelles-sur-Mer (French pronunciation: [nwajɛl syʁ mɛʁ], literally Noyelles on Sea) is a commune in the Somme department in Hauts-de-France in northern France.

Noyelles-sur-Mer is situated on the coast, facing the English Channel, on the D11 and D40 junction, some 13 kilometres (8 mi) northwest of Abbeville.

On 20 May 1940 at 02:00 in the early morning, Noyelles-sur-Mer became one of the first French settlements on the coast of the English Channel occupied by the Wehrmacht during the Battle of France.

Noyelles has a railway station on the Boulogne–Amiens line. There is also a heritage railway at Noyelles, the Chemin de Fer de la Baie de Somme, which formed part of the Réseau des Bains de Mer system. A dual gauge line goes to Saint-Valery-sur-Somme, and a metre gauge line continues on to Cayeux. Another metre gauge line goes to Le Crotoy. A further metre gauge line, now closed, went to Forest-l'Abbaye, where it connected with the line between Abbeville and Dompierre-sur-Authie.
