The Costa do Sol State Park (Portuguese: Parque Estadual da Costa do Sol [ˈpaʁki estɐduˈaw dɐ ˈkɔstɐ du ˈsɔw], Sunshine Coast State Park) is a state park in the state of Rio de Janeiro, Brazil. It protects a number of fragments of coastal areas in the Atlantic Forest biome that are under intense pressure from urban expansion, but that also have considerable tourism potential.

The Costa do Sol State Park has about 9,840.90 hectares (24,317.4 acres) divided into four sectors, each consisting of one or more separate areas. It covers lands in the municipalities of Araruama, Armação dos Búzios, Arraial do Cabo, Cabo Frio, Saquarema and São Pedro da Aldeia as well as parts of the Atlantic Ocean and the Araruama Lagoon in the state Rio de Janeiro. The Costa do Sol State Park is the first mosaic park in Brazil, made up of discontinuous protected areas. In all there are 27 environmental preservation areas.

The unit protects almost all of the remaining natural ecosystems of the Região dos Lagos (Lake Region), which is under intense real estate pressure. More than half of the park is located in the Massambaba Environmental Protection Area, which covers Saquarema, Araruama and Arraial do Cabo. It contains several species in danger of extinction, including the passarine restinga antwren (Formicivora littoralis), rufous-legged owl (Strix rufipes), fluminense swallowtail (Parides ascanius) and skull tree iguana (Liolaemus occipitalis). There are vestiges of sambaquis, where prehistoric hunters and gatherers lived. The Lagoa Vermelha, in Saquarema, contains limestone rocks formed by microorganisms in shallow seas and lagoons, a rare phenomenon that is important in understanding evolutionary history.
