Trinity Bridge (Russian: Тро́ицкий мост, Troitskiy Most) is a bascule bridge across the Neva in Saint Petersburg, Russia. It connects Kamennoostrovsky Prospect with Suvorovskaya Square. It was the third permanent bridge across the Neva, built between 1897 and 1903 by the French firm Société de Construction des Batignolles. It is 582 meters (1,909 ft) long and 23.6 meters (77 ft) wide.

The bridge takes its name from the Old Trinity Cathedral which used to stand at its northern end. In the 20th century it was known as Equality Bridge (Russian: мост Ра́венства, 1918–1934) and Kirovsky Bridge (Russian: Ки́ровский мост, 1934–1999).

In 1803 the Voskresensky ponton bridge, which was built in 1786 near Voskresensky Prospect (now Chernyshevsky Prospect), was moved to the Summer Garden. In 1825, the ponton Suvorovsky Bridge was built to link Suvorovskaya Square with Troitskaya (Trinity) Square.

In 1892 a contest for constructing a permanent Troitsky Bridge was announced. There were 16 entrants from Russian and European engineers, including one from the French engineer Gustave Eiffel, the creator of the famous Eiffel Tower in Paris. The winner was the out-of-competition conception by Paul Bodin aided by Arthur Flachet, Vincent Chabrol, and Claude Patouillard from the French Société de Construction des Batignolles. Some contributions to their proposal were provided by a team of Russian engineers. A special commission from the Imperial Academy of Arts, including Leon Benois also participated in the project.
