Lieutenant-Colonel Maharaja Rana Shri Sir Natwarsinhji Bhavsinhji Sahib Bahadur, KCSI (30 June 1901 – 4 October 1979) was the last Maharaja of Porbandar belonging to Jethwa dynasty, who ascended the throne of princely state of Porbandar on 10 December 1908 and ruled until his state was merged into India on 15 February 1948.

He first married Rupaliba Sahiba (1898–1943) of Limbdi State in 1920 and, after her death, Anant Kunverba alias Annette de Silva (1911–1989) in 1954.

In the era when only Royals used to hold position of Captains, in a rare gesture of sportsmanship, he stood down from the captaincy in favour of the more talented C.K.

[4][5] Natwarsinhji was an avid painter, author and musician; his literary works include "From the Flow of Life" (1967), "India's Problems: Reflections of an Ex-Ruler" (1970) and "International Solidarity" (1975).

[citation needed] He also took active interest along with Nanji Kalidas Mehta to see that Kirti Mandir is being built in Porbandar, as a memorial to Mahatma Gandhi.
