Tacumshane or Tacumshin (Irish: Teach Coimseáin)[1] is a small village and civil parish in the southeast of County Wexford, Ireland.

In Yola it is listed as "tagh caam seain", meaning in modern English the "crooked house of John".

[citation needed] About two miles away is the townland of Churchtown which was once called Tacumshane.

Tachumshin Lake is commonly visited by bird watchers and attracts some rare American waders in Autumn, as well as internationally important concentrations of Bewick's swans, Brent geese, wigeon, oystercatchers, golden plover and lapwing.
