Porturlin (Irish: Port Durlainne)[1] is a Gaeltacht village and townland on the northwest coast of County Mayo, Ireland.

[3] Following the Irish Rebellion of 1798 watch towers and defence structures were built along the northern coast.

[4] In 1894, the Congested Districts Board set up a processing facility for herring and mackerel in Porturlin, they also operated a lace school in the area.

[4][5] After several iterations, in 1965, Mayo County Council started to construct a fishing pier for use by a greater number of vessels.

[4] Richard Webb, present during the famine years to assess the situation for the Society of Friends, noted that the prime fishing area in Mayo was located off Porturlin, but described the area as almost inaccessible by land.
