Gracilaria multipartita is commonly found in tropical and subtropical regions around the world. It is typically found in the intertidal and subtidal zones of rocky shores, as well as in estuaries and lagoons.

Gracilaria multipartita is commonly found growing attached to rocks or other hard substrates in shallow waters with moderate to high levels of water movement. It can also grow epiphytically on other macroalgae or seagrasses. The species has been introduced to several regions outside its native range, such as the Mediterranean, where it has become established as an invasive species.
