|Tongan Citizenship Act|
|Parliament of Tonga|
|Enacted by||Government of Tonga|
|Status: Current legislation|
Nationality and citizenship in the Kingdom of Tonga are currently defined and regulated by the Nationality (Amendment) Act 2007.
Tonga's Constitution does not include a specific clause on nationality or citizenship. However, clause 29 pertains to naturalisation:

|Issues, rights, and visas|
Specific legislation, therefore, defines nationality and citizenship. The most recent piece of legislation, in 2007, was the Nationality (Amendment) Act, designed to revoke the ban on dual citizenship.
At present, Tongan nationality may be obtained by birth in Tonga to a Tongan parent, by birth abroad to a Tongan parent, by marriage, and by naturalisation. A person born overseas to a Tongan parent automatically obtains Tongan nationality, even if he or she also has the nationality of his or her country of birth.
In February 2008, two former Tongan citizens who had lost their Tongan nationality by obtaining the nationality of other countries (one had become an American, the other an Australian) were the first to re-obtain Tongan nationality through application on the basis of the 2007 Nationality (Amendment) Act. Re-obtaining citizenship in this way entails submitting an application to the King, having this application reviewed by the Minister for Immigration, and swearing an oath of allegiance.
