According to East (1996), the dorcas gazelle still ranges in Algeria, Burkina Faso, Chad, Djibouti, Egypt, Eritrea, Ethiopia, Libya, Mali, Mauritania, Morocco, Niger, Somalia, Sudan, Tunisia and Western Sahara; its occurrence in Nigeria is very doubtful, while it is considered extinct in Senegal. Its geographical distribution was acquired from Yom-Tov et al. (1995). After Dr. R. East’s revision (23 June ‘97) of the map, the entire range was marked as "possible presence" and the southernmost edges were corrected according to country maps in East (1988) and East (1990).

The species occurs in grassland and steppe, in wadis and mountain desert and in semi-desert vegetation. It is not well adapted to life in absolute desert (Osborn & Helmy, 1980; Loggers et al., 1992; Haltenorth & Diller, 1980; Kingdon, 1997; East, 1988, 1990; Yom-Tov et al., 1995).
