Philip Louis of Schleswig-Holstein-Sonderburg-Wiesenburg (born 27 October 1620 in Beck; died: 10 March 1689 in Schneeberg) was the founder and first duke of the line Schleswig-Holstein-Sonderburg-Wiesenburg. His branch of the House of Schleswig-Holstein-Sonderburg is named after Wiesenburg Castle, near Zwickau.
Philip Louis was the youngest son of Duke Alexander of Schleswig-Holstein-Sonderburg (1573–1627) from his marriage to Dorothea (1579–1639), daughter of Count John Günther I of Schwarzburg-Sondershausen.
Philip Louis spent his youth at various courts in Hesse. In 1663 he acquired the district of Wiesenburg, with Wiesenburg Castle and the city of Kirchberg and 20 villages from Elector John George II of Saxony, with whom he had a very good relationship. Wiesenburg Castle became his seat and gave its name to his family line.
In 1668, he appointed Johann Winckler to educate his sons at the Wiesenburg Castle. He invested in the mining industry in Schneeberg and Neustädtel. Initially, it appeared to be a failure, but in the 1670s he made large profits and became a wealthy mining entrepreneur. He had his castle thoroughly renovated.
Until 1672, Philip Louis was an imperial field marshal lieutenant in a Cuirassiers regiment. He had his castle thoroughly renovated and in 1675, he sold Wiesenburg (both the Castle and the district) for 100000Taler to his eldest son, Frederick (1651–1724). In 1686, he purchased Oberkotzau. He lived until his death on 10 March 1689 with his old friend Veit Hans Schnorr von Carolsfeld in Schneeberg.
