This is a list of Hanoverian princes from the accession of George III to the throne of the Kingdom of Hanover in 1814. Individuals holding the title of prince will usually also be styled "His Royal Highness" (HRH). The wife of a Hanoverian prince will usually take the title and style of her husband. Despite Hanover's annexation by Prussia in 1866, male-line descendants of George III continue to style themselves as a prince or princess of Hanover.
The title Prince of Hanover and the use of the style "Royal Highness" has generally been restricted to the following persons:
| Prince of Hanover by the sovereign |
| Prince of Hanover from birth |
| (†) - In Letters Patent dated 20 November 1917, King George V restricted the title of Prince to the children of the sovereign, the children of the sovereign's sons, and the eldest living son of the eldest son of the Prince of Wales. |
| (‡) - By an Order in Council dated 28 March 1919, as authorized by the Titles Deprivation Act 1917, King George V suspended the British peerage titles, princely dignities and honours of those who sided with Germany in World War I. |
