The Archdiocese of Huambo (Latin: Archidioecesis Huambensis) is a Latin Metropolitan archdiocese of the Roman Catholic Church in western Angola.

The cathedral see of the archbishop is the Marian Cathedral of the Conception of Our Lady (Portuguese: Sé Catedral de Nossa Senhora da Conceição), in Huambo.

By 2019, the archdiocese had approximately 1.1 million Roman Catholics and 88 diocesan priests.

On 4 September 1940, the Diocese of Nova Lisboa was established on assembled territories split off from the Diocese of São Paulo de Loanda and mission sui iuris of Cunene, mainly to serve the growing European population in what was then the colony of Portuguese Angola.

As time went on, it shed territory due to the creation of other dioceses :

• on 27 July 1955 to establish the then Diocese of Sá da Bandeira (now the Archiocese of Lubango)
• on 6 June on 1970 to establish its future suffragan diocese, the Diocese of Benguela
• on 10 October 1975 to establish the Diocese of Serpa Pinto (later renamed the Diocese of Menongue) and the Diocese of Pereira de Eça (later renamed the Diocese of Ondjiva).

On 3 February 1977, the Diocese of Nova Lisboa was promoted and renamed the Metropolitan Archdiocese of Huambo.

In June 1992, it enjoyed a Papal visit from Pope John Paul II.

The archdiocese has an area of 35,770 square kilometers and comprises most of Huambo Province, including the following municipalities:

• Huambo
• Bailundo
• Ekunha
• Caála
• Katchiungo
• Londuimbali
• Longonjo
• Mungo
• Tchicala Tcholohanga
