Frederick IV, Elector Palatine of the Rhine (German: Kurfürst Friedrich IV. von der Pfalz; 5 March 1574 – 19 September 1610), only surviving son of Louis VI, Elector Palatine and Elisabeth of Hesse,^[1] called "Frederick the Righteous" (German: Friedrich Der Aufrichtige; French: Frédéric IV le juste).

Born in Amberg, his father died in October 1583 and Frederick came under the guardianship of his uncle, John Casimir, an ardent Calvinist, who ruled as regent until his death. The Calvinist mathematician and astronomer Bartholemaeus Pitiscus served as Frederick's tutor and later became court preacher.

In January 1592, John Casimir died and the 17 year old Frederick assumed control of the government of the Electorate of the Palatinate. Frederick continued John Casimir's anti-Catholic measures and in 1608 became the head of the Protestant military alliance known as the Protestant Union. He soon fell prey to alcoholism, leaving state matters largely to his chief minister Christian of Anhalt.^[2] Frederick IV died in 1610 in Heidelberg.

In 1593, Frederick married Louise Juliana of Nassau,^[1] the daughter of William I of Orange and Charlotte de Bourbon-Monpensier. They had eight children:

• Luise Juliane of the Palatinate (Heidelberg, 16 July 1594 - Meisenheim, 28 April 1640),^[1] married in 1612 to Pfalzgraf John II, Count Palatine of Zweibrücken.
• Katharina Sofie of the Palatinate (Heidelberg, 10 June 1595 - Köln an der Spree, 28 June 1626).
• Frederick V, Elector Palatine (Jagdschloß Deinschwang, 16 August 1596 - Mainz, 29 November 1632); married in 1613 Princess Elizabeth of Great Britain (later Queen of Bohemia).^[1]
• Elisabeth Charlotte of the Palatinate (Neumarkt, 19 November 1597 - Crossen an der Oder, 26 April 1660); married in 1616 to Elector George William of Brandenburg^[1]
