Ernest III (IV by some accounts) was the eldest son of Philip I, Herzog von Braunschweig-Grubenhagen in Herzberg, Osterode and part of Grubenhagen, and his second wife, Katharina von Mansfeld, and was born 17 December 1518.
In 1545 his family forcibly reformed the church of St Alexander in Einbeck, and he (or one of his brothers) became Provost (Propst).
He married at Wolgast, on 9 October 1547, Margareta von Pommern-Wolgast and they had only one child that reached adulthood, a daughter:
He succeeded on the death of his father as Duke of Brunswick-Grubenhagen in Herzberg, Osterode and Grubenhagen in 1551, and was recognized as Duke of Brunswick and Luneburg in 1566.
Ernest V died at Herzberg 2 April 1567 and was buried at Agidienkirche, Osterode, perhaps on 4 April. His two surviving younger brothers, Wolfgang and Philipp II, both without male heirs, successively succeeded him in Brunswick-Grubenhagen, and the line died out.
