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).
He served in the Dutch army until he inherited the Dutch from his uncle, Philip of Hohenlohe-Neuenstein. When his father died in 1610, he and his brothers Georg Friedrich (1569–1647) and Kraft (1582–1641) divided the inheritance. Georg Friedrich received Weikersheim; Kraft received Neuenstein and Philip Ernest received the Lordship of Langenburg. He immediately began the construction of Langenburg Castle. He spent much of his time in the Netherlands, until he was relieved of his duties as a colonel by the States-General.
He died in 1628, at the age of 44, in Weikersheim, of a "stone disease". 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.
On 15 January 1609, he married Countess Anna Maria of Solms-Sonnewalde (1585–1634), the daughter of Count Otto of Solms-Sonnewalde. They had the following children:
