Pierre-Gérard Carrier-Belleuse (28 January 1851 in Paris – 29 January 1932 in Paris) was a French painter.
Best known for his ballet scenes and pastels, he also did landscapes, portraits and genre works. Most of his paintings are in private collections. The painter Louis-Robert Carrier-Belleuse was his brother.
Between 1914 and 1916, he and Auguste François-Marie Gorguet proposed, planned and supervised the creation of the Panthéon de la Guerre, which was the world's largest painting (45 ft. high and 402 ft. in circumference) containing almost 5,000 portraits of notable French and Allied wartime figures, mostly sketched from life. Twenty artists played a major role in its production, although many more made contributions. It was exhibited in a specially constructed display building (which was demolished in 1960) next to the Hôtel des Invalides. Later, it made its way to the United States, and reconfigured portions of it may now be seen in the National World War I Museum at the Liberty Memorial in Kansas City. It was his second such work, following the much smaller Panorama de Notre-Dame de Lourdes from 1881.
