The Chapel of St Fyndoca (alternate: Fyndoc, or Findoc) is located on the island of Inishail in Loch Awe, Argyll and Bute, Scotland.
It was the parish church of the parish of Inishail, which included some of the adjacent islands, as well as part of the mainland on each side of the loch. The church is recorded in the mid-13th century, but fell out of use in the 18th century. It is now a ruin, surrounded by a graveyard which contains medieval carved slabs and post-reformation gravestones. The parish is now served by Glenorchy Parish Church at Dalmally. The remains of the chapel and burial ground are protected as a scheduled monument.
In the Origines Parochiales Scotiae, the following was noted:
"The year 1257 is marked by the gift of two churches to the abbey. Another son of Malcolm Macnauchtan, Athe by name, with the assent of his brother, Sir Gilbert, knight, gave to the abbot and canons of Inchaffray Abbey the church of St. Findoc of Inchealt, in the Diocese of Argyll, with all tithes, etc., pertaining to the said church. This is the church of Inishail, a parish which included the island of that name in Lochawe, several smaller islands, and land on both sides of the loch. The parish church was in the island. The church remained the possession of the abbey till the Reformation."
The parish church is mentioned by John of Fordun about 1400. In 1529, Archibald Campbell, 4th Earl of Argyll, granted the lands of Barindryane to one Duncan Makcaus, on condition that he and his heirs maintain the chapel of Saint Fyndoc on Inishail, and have masses said for King James V as well as the Earl's own predecessors and successors. In 1556, the grant was confirmed by Queen Mary.
In 1618, Inishail parish was united with Glen Orchy Parish. In 1736, service was discontinued in the 'ruinous chapel' on the island of Inishail, and a church more commodious for the parish was built at Cladich, on the south side of the loch opposite Inishail.
