Phare de la Croix, Maritime lighthouse in Concarneau, France.

Phare de la Croix is a white cylindrical lighthouse on the port of La Croix in Concarneau, its shaft painted vertically with the red letters "LACROIX". A red metal railing runs around the gallery above the shaft, enclosing a glazed lantern. The tower rises from a low white structure with rough tan stone at its corners and cap, and a blue panel with a white door sits below the shaft.

The lighthouse was built in the 19th century to make night entry into Concarneau harbour safer. It first formed an alignment with the Beuzec lighthouse, which is no longer in service. The alignment now runs with the second Beuzec light, installed in the church bell tower.

The lighthouse takes its name from the port de la Croix where it stands, beside the chapel of the same name. The lower wall carries a small blue sign reading "Croix" over "de la Croix", and the shaft bears the red letters "LACROIX". Nearby are the Rodel beach, the former sailors' shelter now used as a youth hostel, and the Marinarium.
