The Diocese of Guarda (Latin: Dioecesis Aegitaniensis) is a Latin Church diocese of the Catholic church in central eastern Portugal, a suffragan in the ecclesiastical province of the Latin Patriarchate of Lisbon in southern Portugal.

The present episcopal seat is in Guarda Cathedral (Portuguese: Catedral de Nossa Senhora da Consolação) in the city of Guarda. The diocese also contains the Church of São Luís in Pinhel, once the cathedral of the former diocese of Pinhel, absorbed into the diocese of Guarda in 1881.

As per 2014, it pastorally served 253,300 Catholics (96.0% of 263,900 total) on 6,759 km² in 361 parishes and 3 missions with 140 priests (126 diocesan, 14 religious), 17 deacons, 133 lay religious (26 brothers, 107 sisters) and 5 seminarians.

• Possibly in 550, no later than 569, a Diocese of Egitânia (viz.), with see in present Idanha-a-Velha, was established under the Kingdom of the Suebi and maintained by the Visigothic Kingdom which absorbed it by 585. However, due to the Moorish conquest, in 715 it was suppressed, its Cathedral of Idanha-a-Velha later converted into a mosque.
• In 1199 that was nominally restored as Diocese of Guarda, which claimed the apostolic succession but switched the see to Guarda where it built a new cathedral, without awarding even co-cathedral status to the old see.
• On 1549.08.21 it lost territory to establish the Diocese of Portalegre
• On 1881.09.30 it gained territory from the Diocese of Coimbra and gained territory from the suppressed Diocese of Pinhel.
