In the decades following his death, branches of the Irish National Land League were named in Mitchel's honour. There are at least ten Gaelic Athletic Association clubs named after Mitchel, including one based in his home town, Newry and two in County Londonderry, his county of birth – one in Claudy and another in Glenullin. Mitchel Park is named after him in Dungiven, near his birthplace, as is Mitchell County, Iowa, in the United States. Fort Mitchel on Spike Island, cork from which he was transported in 1848 is named in his honour.
