Sgiath Chùil is a mountain situated in the southern highlands of Scotland.

It stands within Loch Lomond and the Trossachs National Park, on its northern border.

Sgiath Chùil qualifies as a Munro, at a height of 921 metres (3,022 ft), and with prominence of 312 metres (1,024 ft), as a Marilyn.

In Sir Hugh Munro's original list of peaks in Scotland with a height over 3,000 feet (914 m) that was published in the Scottish Mountaineering Club Journal in September 1891, Sgiath Chùil was listed as a top, with Meall a' Churain listed as the mountain and higher point.

This error was corrected when the first revision of the list was published in 1921.
