Earl of Norbury, in the County of Tipperary, is a title in the Peerage of Ireland.

It was created in 1827, along with the title Viscount Glandine, of Glandine in the King's County, for the Irish politician and judge John Toler, 1st Baron Norbury, upon his retirement as Chief Justice of the Common Pleas in Ireland.

[2] Moreover, his wife, Grace Toler (née Graham), had been created Baroness Norwood, of Knockalton in the County of Tipperary, in the Peerage of Ireland in 1797, with remainder to the heirs male of her body.

[3] By the time Lord Norbury was raised to the Earldom, his wife had died and their eldest son had succeeded her as 2nd Baron Norwood.

He was shot "by an assassin, in his own plantation" at Durrow Abbey, County Offaly in 1839.
