Charline Simone Rosemonde Mignot (born 20 April 1995), better known as Vendredi sur Mer (French for "Friday by the Sea"), is a Swiss singer-songwriter and photographer.

Charline Mignot was born in Romandy, a Francophone part of Switzerland, where she lived until she moved to Lyon where she attended an art school.

She began her career as a photographer, notably working with the French luxury goods manufacturer, Hermès.

Inspired by a meeting with her manager who appraised her homemade song made with a friend, she decided to take her first steps in the music industry.

The cultural magazine PopMatters likened Mignot's work to that of the French band La Femme.
