St Luke's is an area in central London in the Borough of Islington. It lies just north of the border with the City of London near the Barbican Estate, and the Clerkenwell and Shoreditch areas. The area takes its name from the now redundant parish church of St Luke's, on Old Street west of Old Street station. Following the closure of the church, the parish was reabsorbed into that of St Giles-without-Cripplegate, from which it had separated in 1733.
