Jean-Delphin Alard (8 March 1815 – 22 February 1888) was a French violinist, composer, and teacher.

He was the son-in-law of Jean-Baptiste Vuillaume, and had Pablo de Sarasate amongst his students.

From 1827 he was a pupil of F. A. Habeneck at the Paris Conservatoire, where he succeeded Pierre Baillot as professor in 1843, retaining the post till 1875.

His playing was full of fire and point, and his compositions had a great success in France, while his violin school had a wider vogue and considerably greater value.

Mention should also be made of his edition in 40 parts of a selection of violin compositions by the most eminent masters of the 18th century, Les Maitres classiques du violon (Schott).
