Jacques, Hereditary Prince of Monaco, Marquess of Baux (Jacques Honoré Rainier; born 10 December 2014), is the heir apparent to the Monegasque throne. He is the son of Prince Albert II and Princess Charlene, and twin brother of Princess Gabriella. He also holds the title of Marquess of Baux, which all the heirs apparent to the crown of Monaco have held since 1643.


On 30 May 2014, it was announced that Princess Charlene was pregnant. After much speculation, it was confirmed, on 9 October 2014, that the couple was expecting twins by the end of the year.

On 21 November 2014, the palace announced that each twin would have the right to a salvo of 21 cannon shots at birth. In addition, the day would be declared a holiday. On 10 December 2014, Jacques was born at Monaco's Princess Grace Hospital Centre, two minutes after his sister Gabriella.

The Prince's Palace of Monaco released a statement describing how the birth was to be celebrated in the principality. 42 cannon shots (21 for each child) were to be fired from the Fort Antoine and church bells were to ring for fifteen minutes, followed by boat horns. The twins were presented on 7 January 2015 which was declared a public holiday in Monaco.


The newborn prince was baptized Jacques Honore Rainier. Princess Charlene revealed that she chose the name Jacques, a name that is common in her homeland. The names Honore and Rainier are common among previous rulers of Monaco. He received the title Marquess of Baux from his father.

The twins were baptized at the Cathedral of the Immaculate Conception on 10 May 2015. At this occasion, he was awarded the Grand Cross of Grimaldi. A certified copy of this legal document is safeguarded in the Monaco cathedral, while another is at Bank of Monaco-Credit Suisse.
