The name Teith is obscure,[1] but may come from the Scottish Gaelic Uisge Theamhich, which translates into English as the "quiet and pleasant water".

The Teith continues to Deanston and Doune where the Ardoch Burn meets it, before its confluence with the (smaller) Forth upstream of Stirling.

[2] The Teith is renowned for its fishing and for the splendid arched bridge 1⁄2 mile (800 metres) southwest of Doune.

[4] The 'Brig o' Teith' was constructed in 1535 by Robert Spittal, a Royal tailor to Margaret Tudor, wife of James IV.

According to Charles Rogers in A Week at Bridge of Allan (1851), a ferryman refused Spittal passage across the Teith as he did not have his purse and could not pay.
