Henry Ernest, Count of Stolberg (20 July 1593 in Schwarza – 4 April 1672 in Ilsenburg) was a German nobleman.
From 1639 to 1645, Henry Ernst and his younger brother John Martin jointly ruled the County of Stolberg.
On 31 May 1645, they divided their inheritance, with Henry Ernest receiving the County of Wernigerode and Hohnsteiner Forest.
They had two sons, Ernest and Louis Christian, and one daughter, Anna Eleonore, who married Emmanuel, Prince of Anhalt-Köthen in Ilsenburg on 23 March 1670.
As there was no primogeniture in Stolberg, his sons jointly inherited the county when Henry Ernest died in 1672.
