'''Rainier III''' (Rainier Louis Henri Maxence Bertrand Grimaldi;<ref>{{Britannica |title=Rainier III, prince de Monaco}}</ref> 31 May 1923 – 6 April 2005) was [[Prince of Monaco]] from 1949 to his death in 2005. Rainier ruled the [[Principality of Monaco]] for almost 56 years.

Rainier was born at the [[Prince's Palace of Monaco]], the only son of [[Princess Charlotte, Duchess of Valentinois|Hereditary Princess Charlotte]] and [[Prince Pierre, Duke of Valentinois|Prince Pierre]]. During his reign, he was responsible for the transformation of Monaco's economy, shifting from its traditional [[casino gambling]] base to its current status as a [[tax haven]] and cultural destination. The Prince also coordinated the substantial reforms of [[Monaco's constitution]], which limited the powers of sovereign rule.
