Henri Foucault (? – c. 1719 or 1720) was a French merchant, sheet music publisher (around 1690) and stationer. His shop was located rue Saint-Honoré, under the sign À la règle d’or. He was condemned for publishing and selling "Airs de musique" of which Jean-Christophe Ballard held the privilege (28 June 1690 judgment). On 15 July 1721, the widow Foucault, then remarried, sold the store and the funds to François Boivin and his uncle, Michel Pignolet de Montéclair, for their music publishing house established the same year.
