Pierre Bullet (French pronunciation: [pjɛʁ bylɛ]; c. 1639 – 1716) was a French architect. He was one of the students of François Blondel and became a member of the Académie Royale d'Architecture in 1685. Among his works are the Château de Champs-sur-Marne and the Porte Saint-Martin.

Pierre Bullet's father, Martin Bullet (active in 1608, died after 1639), was a master builder in Paris. At an early age, Pierre Bullet became a student of François Blondel, who was more a theoretician, while Bullet was described as an expert dessinateur et apparailleur (draftsman and equipment operator).

Bullet directed the construction work of the Porte Saint-Denis, built according to the plans and drawings of Blondel, in 1672. Two years later, in 1674, he provided the plans for the Porte Saint-Martin and directed the work. The French architectural historian Maurice Du Seigneur wrote: "This monument is the most important work that Bullet left us; of less grandiose proportions than the Porte Saint-Denis, the Porte Saint-Martin presents a very remarkable aspect of decorative simplicity."

In 1675, he made the high altar of the church of the Sorbonne, as well as the decoration of the two chapels of the transept of the church of Saint-Germain des Prés.

Between 1676 and 1679, he was in charge of the construction work of the Quai Pelletier; in 1676 he designed a Doric door, to serve as an entrance to the building of the pump on the Pont Notre-Dame.

In 1681, he studied the preliminary project of the church of the general novitiate of the Reformed Dominicans; the first stone of this building was laid on 5 March 1683, and the work continued, under the direction of Bullet, who was not to see his work completed. It was not until 1770 that Brother Claude, a Dominican, built the portal of this church which today bears the name of Saint-Thomas-d'Aquin.

From 1684 to 1687, he had the old Saint-Michel fountain built, now destroyed.

He was admitted to the Royal Academy of Architecture on 23 February 1685.
