Zangezur National Park (Azerbaijani: Zəngəzur Milli Parkı) is a national park in Azerbaijan. It was established as the Ordubad National Park on an area of 12,131 hectares (121.31 km) in Ordubad District of the Nakhchivan Autonomous Republic on June 16, 2003. On 25 November 2009 it was enlarged to 42,797 hectares (427.97 km) and renamed Zangezur National Park. This park is located in a mountainous area. It is cold in the winter and hot in the summer. The temperature changes between -30 °C and -10 °C in January and 10 °C 25 °C in July. The annual precipitation is 300–800 mm. The running water comes from the Gilanchay, Vanadchay, Duylunchay, Aylishchay, Ganzachay, Kotamchay, Kilitchay, and Ordubadchay rivers. Rain and melting snow constitute the main parts of these rivers.

According to a 2010 USAID report (which described Azerbaijan's national parks as "so-called national parks"), public access to the Ordubad National Park is all but impossible, since it requires a personal letter "obtained far in advance of a projected visit, and often refused" from the Minister of Azerbaijan's Ministry of Ecology and Natural Resources (MENR), but this is very difficult to obtain for NGOs, international donors, or anyone outside of the government.

In addition to the rich flora and fauna of the Zangezur National Park is rich with natural and historical monuments.
