Nawanagar was an Indian princely state in the historical Halar region, located on the southern shores of the Gulf of Kutch.

Nawanagar was founded in 1540 by Jam Sri Rawalji, a descendant of the Jadeja ruler of Kutch, and was thereafter in an almost constant state of war with its neighbours and with the Mughal Empire.

After his death, in 1933, he was succeeded by his nephew Jam Saheb Shri Sir Digvijaysinhji, who became its chancellor (1937–1944) and continued to promote the octet circle in excellence in cricket, academics and welfare.

Afterwards, the late ruler, Digvijaysinhji, served as the first Rajpramukh of Kathiawad, then represented his country at the United Nations.
