Philip Ernest, Count of Hohenlohe-Langenburg (11 August 1584 in Langenburg – 29 January 1628 in Weikersheim), was Count of Hohenlohe-Langenburg and was the fourth son of Wolfgang, Count of Hohenlohe-Weikersheim (1546–1610), who later became regent of the county of Weikersheim and his wife Magdalena of Nassau-Dillenburg (1547–1643).

When his father died in 1610, he and his brothers Georg Friedrich (1569–1647) and Kraft (1582–1641) divided the inheritance.

He spent much of his time in the Netherlands, until he was relieved of his duties as a colonel by the States-General.

He was buried, together with his wife, in the crypt of the church in Langenburg.

A stone monument commemorating the couple can be found behind the altar.
