Jean-François Alfred was a French playwright. He was the nephew of fellow playwright Eugène Scribe.

As a law student and a lawyer's clerk, Bayard wrote with passion for the theatre and, after several attempts, had a great success at the Gymnase theatre, with La Reine de seize ans (1828, in-8°). One of the most fertile-minded and skilful vaudeville writers of his era, he made a close friendship with Eugène Scribe, often collaborating with him on plays and marrying his niece.

Belonging to the school of Dancourt and Picard, he wrote with extreme ease, producing more than 200 plays for several theatres, sometimes alone, sometimes in collaboration. Many of his plays were remarked upon for their witty cheerfulness, and for not excluding sensitivity and everything else that was in vogue in the 19th century. He most often wrote vaudevilles, though he also had success with drama and even high comedy. In 1840, he collaborated with Georges Henri Vernoy de Saint-Georges on the libretto for Gaetano Donizetti's opéra comique La fille du régiment.

Despite his intensive writing schedule, Bayard devoted a large part of his time to the SACD, and was over many years one of the most active commissioners of new work from them. In this role, nearly all works on his life state that he competed with the directors of Paris's theatres.

In 1857 having his family's fortunes fallen on hard times, Bayard was forced to accept a job offer as director of the théâtre des Variétés. Although he only held the job for a short time, Bayard signaled his tenure with happier results than many who held it longer. After having begun to rehabilitate public opinion towards this theatre, which had fallen from the first rank of the théâtres des boulevards, he later felt it impossible to reconcile his writing and his schedule as an author with the demanding duties of a director and decided to leave the post. However, his last administrative act as director - choosing one of his most witty collaborators, his friend Dumanoir, as his successor - was also a happy one for the theatre. Dumanoir completed Bayard's work, allowing the théâtre des Variétés to regain its forgotten splendours.

Bayard also published articles in several literary journals, and poems and verse dramas in several anthologies. 

In 1857 Bayard was named a member of the Légion d'honneur.
