Porto Katsiki (Greek: Πόρτο Κατσίκι) is a remote beach located on the south-western coast of the Ionian island , Apollonion municipality of the island Lefkada. Since the creation of a sealed road during the mid 1990's, this remote beach has become one of the premier tourist destinations on the island.

The beach is accessed from the car park via steep steps that hug a rugged cliff face. The waters of Porto Katsiki are strikingly clear and the sunsets are frequently dramatic. The beach is composed of fine to medium sized pebbles that are very comfortable to lie on.

The word Katsiki means goat in Greek, and the area was once used by local shepherds to bathe their flocks.
