Stora Gråmunkegränd (Swedish: Great Greyfriar's Alley) is an alley in Gamla stan, the old town in central , Sweden. Stretching west from Västerlånggatan down to Munkbron and Munkbroleden, it is crossed by Stora Nygatan, and forms a parallel street to Storkyrkobrinken and Helga Lekamens Gränd.
The alley is named after the defensive tower Gråmunketornet ("Greyfriar's Tower") located in the city wall which used to pass along the eastern side of today's Västerlånggatan, in its turned named after the Greyfriars abbey on Riddarholmen, at the time called Gråmunkeholmen ("Greyfriar's Islet"). It appears in historical records as grabroder strate ("grey brother's street") in 1420 and gramunka grendenne ("[the] grey monk's alley") in 1456.
The first element, however, doesn't appear until 1728 when the alley south of it (Helga Lekamens Gränd) was being referred as Lilla Gråmnukegränd ("Smaller Greyfriars Alley"), and the part of the alley west of Lilla Nygatan was named Schaleri Gränd after the doctor Peter Schallerus Gripenflycht who owned the property in the western end. The name have been used for the entire extent of the alley since 1885.
On number 5, is a flat with preserved wall paintings and a coffered ceiling from 1580. While sparsely used by the since the city took it over in 1973, as of 2006 the flat will hopefully be made available to the general public.
