Magdalen Bridge /ˈmɔːdln/ spans the divided stream of the River Cherwell just to the east of the City of Oxford, England, and next to Magdalen College, whence it gets its name and pronunciation. It connects the High Street to the west with The Plain, now a roundabout, to the east.

This point of the Cherwell has been used for crossing since ancient times. The first known reference to a bridge goes back to 1004 and originally it was probably a wooden trestle construction or a drawbridge. By the 16th century a late medieval stone bridge had replaced the wooden one. This bridge was about 1,500 feet (460 m) long and was formed by 20 arches.

By the 1770s, the stone bridge was too narrow for the increasing traffic, as it did not allow two vehicles crossing safely. In addition to this, the structure was becoming unsound due to the combination of two factors: a generalized lack of maintenance and the negative effects of regular flooding. Eventually some of the arches of the western side collapsed during the floods of February 1772, making the bridge irreparable.

The present stone bridge was designed by John Gwynn of Shrewsbury with a similar length to the previous one. It has a total of 11 arches of different dimensions distributed as follows. For each of the two branches of the river there are three large semicircular arches plus two smaller ones at each side of the river, originally designed for the towpaths. A central elliptical arch, the only existing in the long central area across the island, completes the structure. This arch only conveys water when the island gets submerged. The original plans of the bridge are in the British Library, 1802 c.17, vol.2, and King's Maps xxxvi, 33 (1).

The bridge, built between 1772 and 1790 by John Randall, originally had a width of 27 feet (8.2 m), which accommodated a single roadway and two pavements. Although the bridge was opened to traffic by the end of 1778, a new scheme for the balustrade and the completion of the south western corner were not finished until 1782 and 1790 respectively.
