Orfasay (Old Norse: Orfyrisey, meaning "tidal island") is one of the Shetland Islands.
Orfasay is a tidal island in Yell Sound, connected to Yell at low tide. This is reflected in the island's name.[1]
It is near the mouth of Hamna Voe and Cuppister in Yell.
The island is uninhabited but two structures on the North-West side of the island can be seen. The structures have no roofs, implying that they are ruined buildings and indicating that the island was inhabited in the past.
