BorderIrish or @BorderIrish was the pseudonym of an anonymous satirical author, resident on the island of Ireland, who from 2018 to 2020 wrote in the first person about being the 97-year-old 499 kilometers Irish border between the Republic of Ireland and Northern Ireland (i.e. an anthropomorphism), both on twitter as @BorderIrish and in print with I Am the Border, So I Am (2019); and in particular on the implications of Brexit on the Irish land border.
