Sidi Fredj is a coastal town in Algiers Province, Algeria. It is located within the territory of the municipality of Staouéli, on a presque-isle on the Mediterranean Sea.
Sidi Fredj was the landing spot where the French established their beachhead for the Invasion of Algiers in 1830. A number of ships of the French Navy were subsequently named Sidi Ferruch, the colonial name of the town under French rule, in honour of the event.
