Henry Theophilus Clements PC(I) (1734 – 26 October 1795) was an Anglo-Irish soldier, politician and official in the Dublin Castle administration in Ireland.
He was raised at the family seat at Ashfield Lodge, County Cavan and at Woodville, Lucan, Dublin.
[1][2] In parliament, Clements was a staunch supporter of the Dublin Castle administration, voting against legislative independence and parliamentary reform.
In 1783, he was unseated from Leitrim by a popular petition after being accused of bribing voters; he returned to representing Cavan Borough instead.
In this role he reformed the financial administration in Ireland and was closely involved in developing a national lottery in 1686.
