Eulemur fulvus is found on Madagascar and the Comoro Islands. This species includes five subspecies. They are Eulemur fulvus fulvus (common brown lemurs), Eulemur fulvus albifrons (white-fronted lemurs), Eulemur fulvus collaris (collared lemurs), Eulemur fulvus rufus (red-fronted lemurs), and Eulemur fulvus sanfordi (Sanford's lemurs). They all have their own specific ranges within the larger range shared by the entire species.
Red fronted lemurs (E. f. rufus) are found naturally in western and eastern Madagascar. There is also a small introduced population in Southern Madagascar at the Berenty Private Reserve. Common brown lemurs (E. f. fulvis) are found in northwest portions of Madagascar. White-fronted lemurs (E. f. albifrons) are found throughout most of the remaining northeastern rain forest in Madagascar. Collared lemurs (E. f. collaris) are found in southeastern Madagascar, and Sanford's lemurs (E. f. sanfordi) have a very restricted range in northern Madagascar.
At some points, these subspecies exist sympatrically.
