Merchants' Hall (sometimes Merchants' Arch) is a former 19th century guildhall, now a protected structure, on Wellington Quay in Dublin, Ireland. It is located opposite the Ha'penny Bridge and backs on to Temple Bar. The building was the last of the city guildhalls to be constructed and only operated as a guildhall for a period of 20 years before ceasing as the Merchants' Guild ended its main work, along with the other Guilds of the City of Dublin.
