Henri James Nathaniel Charles, Baron de Rothschild (26 July 1872 – 12 October 1947) was a French playwright who wrote under the pen names André Pascal, Charles des Fontaines, and P.-L.

He was a scion of the English branch of the Rothschild family, being the son of James Edouard de Rothschild (1844–1881) and Thérèse von Rothschild (1847–1931). His paternal grandfather was Nathaniel de Rothschild, originally from London, the founder of the French wine-making branch of the Rothschild family.

He married, in 1895, Mathilde Sophie Henriette von Weissweiller (1872-1926). They had three children:

• James-Henri de Rothschild (1896–1984), who married, in 1923, Claude Dupont (1904–1964) then, in 1966, Yvette Choquet (born in 1939)
