Outjo (Otjiherero: small hills) is a town of 15,000 inhabitants in the Kunene Region of Namibia. It is the district capital of Outjo Constituency. It is best known as the main gateway to Etosha National Park.

The town was founded by Germans under the command of Colonel Theodor von Leutwein in 1897 as a small military base in order to explore the northern area of German South West Africa. The local historical museum (Franke Haus Museum) details the campaign of Major Viktor Franke in Ovamboland.

The "Naulila monument" commemorates the small expedition on the Portuguese fort of Naulila in Angola by Major Viktor Franke in October 1914 following the massacre of a German delegation which had been sent to negotiate a treaty of non-aggression. It is one of the fastest developing towns in the Kunene Region.

South of Outjo is the Ugab River, one of the major rivers of Namibia. The town lies near Gamkarab Cave, known for its stalactites and stalagmites and its pietersite. The caves are on private ground and not open to the public.

Outjo is governed by a municipal council that has seven seats.

Since the independence of the country, Outjo is the only small town in the Kunene Region controlled by the ruling party "SWAPO". The 2015 local authority election was won by SWAPO which gained four seats (1,307 votes). Two seats went to the United Democratic Front (UDF, 706 votes), and the remaining seat was won by the Democratic Turnhalle Alliance (DTA) with 381 votes. SWAPO also won the 2020 local authority election but lost majority control over the municipal council. It obtained 872 votes and three seats. One seat each went to the Landless People's Movement (LPM, a new party registered in 2018, 501 votes), the UDF (392 votes), the Popular Democratic Movement (PDM, the new name of the DTA, 307 votes), and the Monitor Action Group (MAG, 161 votes).
