Prince Philippe of Orléans, Count of Paris (Louis Philippe Albert; 24 August 1838 – 8 September 1894), was the grandson of Louis Philippe I, King of the French. He was Count of Paris, and was a claimant to the French throne from 1848 until his death. He was styled as "King Louis Philippe II", although some monarchists prefer the designation "King Philippe VII".

Prince Philippe became the Prince Royal, heir apparent to the throne, when his father, Prince Ferdinand-Philippe, Duc d'Orléans, died in a carriage accident in 1842. Although there was some effort during the days after the abdication of his grandfather in 1848 to put him on the throne under the name of Louis-Philippe II, with his mother (Helene of Mecklenburg-Schwerin) as Regent, this came to nothing. They fled and the French Second Republic was proclaimed in its stead.

An historian, journalist and outspoken democrat, Philippe volunteered to serve as a Union Army officer in the American Civil War along with his younger brother, Prince Robert, Duke of Chartres. He was appointed as an assistant adjutant general with the rank of captain on 24 September 1861 and served under the name of Philippe d'Orléans, the Count of Paris. He served on the staff of the commander of the Army of the Potomac, Major General George McClellan, for nearly a year. He distinguished himself during the unsuccessful Peninsular Campaign. He resigned from the Union Army, along with his brother, on 15 July 1862. Philippe's history of the Civil War is considered a standard reference work on the subject.
