The Centro Habitat Mediterraneo (CHM; Italian for "Center for Mediterranean Habitat") is an oasis of 20 hectares (49 acres), located on the Italian coast near Rome, included in the Litorale Romano State Nature Reserve and managed by the Italian Bird Protection League (LIPU).

In the 1990s, the area of the Ostia Seaplane Base was occupied by an open landfill site, known for being the scene of the murder of Pier Paolo Pasolini on November 2, 1975.
In 1995 the area caught the attention of an Australian company, which proposed the construction of an oceanarium that would irreparably alter the ecosystem of the mouth of the Tiber. To oppose this proposal, the Ostia delegation of the Italian Bird Protection League (LIPU) proposed the creation of a nature reserve and – after a heartfelt campaign to collect signatures within the XIII Circoscrizione (today the Municipio X) – the project was approved; after the reclamation of the area, the oasis opened in 2001. This was also accompanied by the inauguration of the nearby Marina of Rome, part of a project for the redevelopment of the seaplane base area.

The 20 hectares of greenery, with an artificial pond in the center, are a refuge and a stopping place for various species of animals (mainly birds) and attract professional photographers and birdwatchers from all over the world. Inside the oasis there is the "Pier Paolo Pasolini" Literary Park, inaugurated on November 2, 2005, where a concrete sculpture was erected to commemorate the well-known Italian writer and director. The sculpture, the work of Mario Rosati, was damaged in 2016 by some vandals but was restored over the following year.
In 2016 a bunker dating back to World War II, probably for anti-aircraft use, was unearthed in the oasis.
