The National Marine Park of Zakynthos (Greek: Εθνικό Θαλάσσιο Πάρκο Ζακύνθου) founded in 1999, is a national park located in Laganas bay, in Zakynthos island, Greece. The park, part of the Natura 2000 ecological network, covers an area of 135 square kilometres (52 sq mi) and is the habitat of the loggerhead sea turtle (Caretta caretta). It is the first national park established for the protection of sea turtles in the Mediterranean.

Zakynthos Marine Park encompasses the marine area of the Bay of Laganas, on the southern shores of the island of Zakynthos, and hosts one of the most important sea turtle nesting beaches in the Mediterranean. The nesting habitat in the bay comprises six discrete beaches: Gerakas, Daphni, Sekania, Kalamaki, E. Laganas and Marathonissi islet, totalling about 5 km (3 mi) in length, of which Sekania is rated amongst the world's highest loggerhead nesting concentrations. Apart from the nesting areas the park encompasses the wetland of Keri Lake and the two small islands of Strofadia, which are located 50 km (31 mi) south from the island of Zakynthos.

The marine park is composed of three marine zones (A, B, C) in the Bay of Laganas, in addition to the strictly protected nesting areas, as well as the terrestrial and peripheral zone. For the protection of the ecosystem, fishing activities are strictly prohibited inside each of the marine zones.

The area is home to the endangered loggerhead sea turtle (Caretta caretta), which is considered one of the oldest forms of life on planet. The marine park hosts annually 900 to 2,000 nests, which represents an average of eighty percent of the nest total of Mediterranean loggerhead population. The loggerhead spends most of its life at sea, but females lay their eggs on Laganas bay at night from May to August.

Furthermore, the area is characterised by a variety of habitats of interest including sand dunes, Posidonia oceanica beds, the critically endangered sea daffodil (Pancratium maritimum), submerged reefs, as well as hundreds of species of flora and fauna, some of which are of great importance. It should also be noted that a resident population of the critically endangered species of monk seal, Monachus monachus is present at the west coast of Zakynthos.
