Rocky headland and small fishing place on the west coast of the Isle of Man, near Dalby.

The Niarbyl was once home to a small fishing fleet. William Cashen, born at Dalby in 1838, moved there with his family while still young. Cashen later recalled a fishing community in which Manx remained the everyday language; he himself knew only Manx until he was about nine years old.

Cashen described the Niarbyl as the headquarters of the Dalby fishermen. A tradition recorded from him concerned a fleet from Port Masooyl, the older name he gave for the Niarbyl, which went out fishing on a Sunday night. A south-easterly storm drove the boats beneath Cronk-yn-Irree-Laa, where part of the cliff at Garroo Clagh was said to have fallen into the sea and swamped them.

The story was used to explain the strong reluctance of Manx fishermen to fish on Sunday. Cashen said the place where the cliff had fallen was pointed out to him as a child by old men then over seventy, together with a warning never to fish on a Sunday night.

Another piece of fishing satire connected the Niarbyl with Hango Hill. Cashen recorded a story that the gallows at Hango Hill were washed away by a heavy sea and came ashore at the Niarbyl. Southside fishermen then mocked the westside men with verses claiming that even the gallows had gone round west to hang the men of Dalby.

The coast itself was noted for erosion and change. A nineteenth-century geological map explanation listed Niarbyl Point among places where sea action had altered the outline of the Island.
