The common dwarf mongoose (Helogale parvula) is a mongoose species native to Angola, northern Namibia, KwaZulu-Natal in South Africa, Zambia and East Africa. It is part of the genus Helogale, along with the Ethiopian dwarf mongoose.

The common dwarf mongoose has soft fur ranging from yellowish red to very dark brown. It has a large pointed head, small ears, a long tail, short limbs and long claws. With a body length of 18–28 cm (7.1–11.0 in) and a weight of 210–350 g (7.4–12.3 oz), it is Africa's smallest member of the order Carnivora.

The common dwarf mongoose ranges from East to southern Central Africa, from Eritrea and Ethiopia to the provinces of Limpopo and Mpumalanga in the Republic of South Africa. The common dwarf mongoose inhabits primarily dry grassland, open forests and bushland up to an elevation of 2,000 m (6,600 ft). It is especially common in areas with many termite mounds, its favorite sleeping place. It avoids dense forests and deserts.
