Viscount Clare

Viscount Clare was a title in the Peerage of Ireland, created twice.

The titles of Viscount Clare and Baron Moyarta were conferred on Daniel O'Brien, a younger son of Connor O'Brien, 3rd Earl of Thomond, on 11 July 1662.

In 1741 the titular sixth Viscount Clare also succeeded as heir-male to the Earls of Thomond, and assumed that title as well, though because of his grandfather's attainder the succession was not recognised in Ireland.

The claim to the viscounty and the earldom became dormant on the death of the titular seventh Viscount in 1774, and the headship of the O'Brien dynasty passed to the Earls of Inchiquin.

The titles of Viscount Clare and Baron Nugent were conferred on the politician Robert Craggs-Nugent on 19 January 1767.
