Tyholland (Irish: Tigh Thalainn, meaning 'Talainn's house'), also known as Tehallan, is a small parish in County Monaghan, Ireland.

It borders directly on Tynan in County Armagh, Northern Ireland, in the east.

O’Donovan Rossa was an important visitor to the Rice household and to the parish during the Fenian period.

The Rice family were deeply involved in the political life of County Monaghan, and a large Celtic Cross at Tyholland Parish Church is a commemoration of the work done by them.
