Tynagh (Irish: Tíne)[2] is a village and electoral division in south-east County Galway in Ireland.

[2] Recorded as Tyneaach (1565), Teacneaghe (1543), Theaneac (1541),[2] its current name is a contraction of Teach nEachach, 'Eochu's house'.

[3] From 1965 to 1981 the mines were managed by the Northgate Group subsidiary Irish Base Metals Ltd.[3] For almost twenty years Irish Base Metals Tynagh Ltd was a major source of employment for east Galway.

[4] In 2004, after lying dormant for over twenty years, part of the site was redeveloped for industrial use with Sperrin Galvanisers (Ireland) Ltd opening a steel galvanising plant, and Tynagh Energy Ltd a combined cycle gas turbine (CCGT) power plant, the first in Galway.

Also during this period, Tynagh had six members on the Galway team that won the All-Ireland Senior Hurling Championship in 1923, another unrivalled county record.
