Mar Chiquita is a coastal lagoon in the southeast province of Buenos Aires in eastern Argentina. It is located by the Atlantic coast, 30 km north of Mar del Plata.
The area is a natural reserve where a number of animal species live around Mar Chiquita. There is a small resort on the southern side of the lagoon with population of 487 people as of 2010.
