Eitel Friedrich was the eldest son of Prince Johann Georg, Prince of Hohenzollern-Hechingen (1577–1623) and Countess Franziska von Salm-Neufville (d. 1619). His father placed particular emphasis on a good education and the prince was sent to the universities of Vienna and Ingolstadt for this purpose. Educational trips to Italy and France also followed.
Eitel Friedrich succeeded his father as Prince of Hohenzollern-Hechingen in 1623. He also commanded an infantry regiment in the service of Emperor Ferdinand II. Eitel Friedrich was loyal to the Catholic Church and therefore supported the Habsburg during the Thirty Years' War.
His power base, the Hohenzollern Castle, was strategically highly significant. The principality was surrounded by Protestant neighbors. In the war, the fortress developed into a focal point and was besieged and devastated by the Swedes and Württembergers in 1634. The castle was recaptured by Imperial troops the next year, and remained under Habsburg control until 1798 against a payment of 5,000 guilders annually.
The Thirty Years' War had impoverished the people in Hohenzollern-Hechingen and Eitel Friedrich was also faced with serious financial problems, forcing him to sell several attractive fiefs.
In 1653, Eitel Friedrich became a Prince of the Holy Roman Empire and was admitted to the Imperial Diet in Regensburg.
In 1661, Eitel Friedrich was wounded in České Budějovice and died shortly after. He left no male heirs and was succeeded as a Prince by his brother Philipp.
On 19 March 1630, he married in Boutersem Maria Elisabeth II van den Bergh (1613–1671), daughter of Hendrik van den Bergh and Margravine of Bergen Op Zoom. With her he had the following children:
