The Holy Loch (Scottish Gaelic "An Loch Sianta/Seunta") is a sea loch in Argyll and Bute, Scotland.
Robertson's Yard at Sandbank, a village on the loch, was a major wooden boat building company in the late 19th and early 20th centuries.
During World War II, the loch was used as a submarine base. From 1961–1992, it was used as a US Polaris and Poseidon nuclear submarine base. In 1992, the Holy Loch base was deemed unnecessary following the demise of the Soviet Union and subsequently closed.
