Merton Street is an historic and picturesque cobbled street in central Oxford, England. It joins the High Street at its northeastern end, between the Ruskin School of Drawing and Fine Art (together with the Examination Schools) and the Eastgate Hotel at the historic east gate of the city. It then runs east-west, parallel and to the south of the High Street for most of its length.
Merton College, one of Oxford's older colleges, is situated to the south of the street. To the west of Merton, Corpus Christi College, one of Oxford's smallest colleges, also fronts onto the street. At the very western end, actually in Oriel Square, is an entrance to Christ Church, Oxford's largest college. At the eastern end can be found the notorious 'Pink House', as well as an entrance to University College.
Logic Lane (through University College, which backs onto the street) and Magpie Lane, both narrow lanes, lead off the street to the north. Also located here is the Merton Street tennis court, a rare example of an extant real tennis court. To the south is Merton Grove (opposite Magpie Lane), providing pedestrian access between Merton College and Corpus Christi College to Christ Church Meadow to the south.
The street is designated the A420 due to the blockage of the High Street to normal traffic. To the west it continues through Oriel Square, where Oriel College is located.
