Prince Emmanuel of Orléans, Duke of Vendôme (Philippe Emmanuel Maximilien Marie Eudes; 18 January 1872 – 1 February 1931) was a French royal from the  House of Orléans.
Emmanuel was born in
Obermais, Meran on 18 January 1872. He was the second child and only son of Ferdinand Philippe d'Orléans, Duke of Alençon and his wife Duchess Sophie Charlotte in Bavaria. His mother was the famed  duchesse d'Alençon who died in a fire at a charity bazaar in Paris on 4 May 1897. His older sister, Louise d'Orléans, married Prince Alfons of Bavaria. 
His paternal grandparents were
Prince Louis, Duke of Nemours (son of Queen Maria and King Louis Philippe, who was forced to abdicate after the outbreak of the French Revolution of 1848) and  Princess Victoria of Saxe-Coburg and Gotha (a first cousin of Queen Victoria). His maternal grandparents were  Duke Maximilian Joseph in Bavaria and Princess Ludovika of Bavaria. 
The Duke was a Major in the
Austro-Hungarian Army, however, he was not allowed to serve in World War I due to an 1886 law barring all princes of the two former sovereign houses of France from being permitted serving their county in the army or navy or hold office in the French government. The Prince, undeterred, volunteered with the French Red Cross, was appointed a principal delegate on the Belgian front and served as a director of the Franco-Belgian Hospital in Calais.  
In 1926, he led an excavation party that unearthed the village of
Roquebillière, in the Alpes-Maritimes department, where several Roman tombs were found containing rare jewels, vases and objects d'art. 
On 12 February 1896, he married
Princess Henriette of Belgium (1870-1948) in Brussels. Henriette was a daughter of Prince Philippe, Count of Flanders and Princess Marie of Hohenzollern-Sigmaringen, and the sister of King  Albert I of Belgium. Together, they were known as the Sporting Duke and Duchess, and had four children:  
Princess Marie-Louise (1896-1973), who wed Prince Philip of Bourbon-Two Sicilies (1885-1949) on 15 January 1916. Before their marriage was annulled in 1926, they had children together.  Princess Sophie (1898-1928), who died unmarried in
Lugrin in 1928. In 1921, she was rumored to have been engaged to the  Crown Prince and Regent of Serbia.  Princess Geneviève (1901-1983), who wed Antoine, Marquis de Chaponay (1893–1956) in Neuilly, France on 2 July 1923. Antoine, a widower of Diane de Cossé Brissac, and Geneviève had children together.
Prince Charles-Philippe (1905-1970), Duke of Nemours, who wed non-dynastically Marguerite Watson (1899-1993), daughter of Garrett Fitzgerald Watson of Richmond, Virginia, in Paris on 24 September 1928,  without issue.  
The couple had estates in Belgium, France and Switzerland until after
World War I, when their fortune diminished rapidly and they were forced to sell some properties.
Philippe died unexpectedly in 1931 from heart failure after catching a cold, in
Cannes, France. He is buried in the  Chapelle Royale de Saint Louis, in Dreux. His widow, Henriette Marie of Belgium died aged 77, on 28 March 1948, in Sierre, Valais, Switzerland.
