The Old Providence McBean Lagoon National Natural Park (Spanish: Parque Nacional Natural Old Providence McBean Lagoon) is a national park located on the northeast side of Providencia Island in the Archipelago of San Andrés, Providencia and Santa Catalina, Colombia.

[1] The area covers 9.95 km2 (3.84 sq mi) (of which 9.05 are maritime)[2] and was declared a national park 1995, partly as a social defense against increased human activity in the form of time-sharing that would destroy a significant part of the area's mangroves.

Noteworthy marine species include: Audubon's shearwater, magnificent frigatebird, brown booby and royal tern; non-marine: green heron and bananaquit (Coereba flaveola tricolor).

[6] The extensive area of marine grasses around the lagoon and bordering mangroves is made up of Thalassia testudinum and Syringodium filiforme.

For conservation reasons, it is not permitted to access the other small islands that form part of the National Park.
