The Third Republic of Vietnam (Vietnamese: Đệ Tam Việt Nam Cộng Hòa, abbreviated DTVNCH), also referred to by its previous name the Provisional National Government of Vietnam (Vietnamese: Chính phủ Quốc gia Việt Nam Lâm thời), is a self-proclaimed government in exile, headquartered in the Little Saigon neighborhood of Orange County, California, with offices in other Little Saigon communities.

The Provisional National Government of Vietnam was formed by former soldiers and refugees from the former South Vietnamese regime on 21 October 1990 and was officially founded on 16 February 1991, led by Prime Minister Đào Minh Quân, who was elected by some of the Vietnamese representatives in the United States.

In November 2018, Prime Minister Đào Minh Quân was reelected as the new President of the newly created Third Republic of Vietnam.

During the ceremony, the US government's staff gave speeches and expressed hope that the newly elected president would work closely with the US.
