Alexandre Jean Albert Lavignac (21 January 1846 – 28 May 1916) was a French music scholar, known for his essays on theory, and a minor composer.
Lavignac was born in Paris and studied with Antoine François Marmontel, François Benoist and Ambroise Thomas at the Conservatoire de Paris, where later he taught harmony.
