Dorset Street (/dɔːrˈsɛt/; Sráid Dorset in Irish) is an important thoroughfare on the north side of Dublin, Ireland, and was originally part of the Slighe Midh-Luchra, Dublin's ancient road to the north that begins where the original bridging point at Church Street is today.

Subsequently, yet prior to the street being given its current name in the 18th century, the road was known as Drumcondra Lane and was shown on maps as such.

Much of the street redeveloped during the Victorian era, with a number of significant buildings built, such as the Gothic style stone-built Dominican priory, designed by J. L. Robinson in 1884–87 at the corner of Dominick Street, while across from it is the red brick Italianate former fire station, designed by C. J. McCarthy and completed in 1903.

Much of the street consists of vernacular Victorian terraces, with shops opening straight onto footpaths at ground-floor level.

Hence under the Housing of the Working Class Act, 1890, the improvement scheme for this area was published in October, but by June there was still only partial approval for the loan in order to commence construction.

A Maldron hotel was built in conjunction with Senator Donie Cassidy now sits on the site of the former National Wax Museum (and before that Plaza Cinema and Bethesda Chapel).
