'''DS Andromedae''' (thường được viết tắt là '''D S And''') là tên của một hệ [[sao đôi]] che khuất nằm trong chòm sao [[Tiên Nữ]] và nó nằm trong cụm sao mở [[NGC 752]]. Nếu ngôi sao thứ nhất trong hệ sao đôi che khuất hoàn toàn ngôi sao thứ hai thì cấp sao biểu kiến của nó là 10,93, còn nếu ngôi sao thứ 2 che khuất hoàn toàn ngôi sao thứ nhất thì cấp sao biểu kiến của nó là 10,71. Còn cấp sao biểu kiến của DS Andromedae là 10,44.
