Johnswell (Irish: Tobar Eoin) is a village in County Kilkenny, Ireland.

On the village green is a powerful spring and well dedicated to John the Baptist which was traditionally the venue for a local "pattern" (religious fair) of note, while the moat north of the village was the site of St John's Eve bonfires.

Maureen Hegarty (1 September 1921 – 14 January 2016), who was a local historian and president of the Kilkenny Archaeological Society, grew up there.
