Maximilian I, Prince of Hohenzollern-Sigmaringen (20 January 1636 – 13 August 1689, in Sigmaringen) was a German nobleman.

Maximilian was the son of Prince Meinrad I (1605-1681) from his marriage to Anna Marie (1613-1682), daughter of Ferdinand Baron of Törring at Seefeld.

He commanded a Dragoon regiment and, like his cousins in the Hohenzollern-Hechingen line, fought under Emperor Leopold I in the Fourth Austro-Turkish War.

After the death of her brother Oswald III in 1712, she inherited the County of 's-Heerenberg, which thus fell to the House of Hohenzollern.

[1] Among his Dutch possessions were the Lordships of Boxmeer, Bergh, Diksmuide, Gendringen, Etten, Wisch, Pannerden and Millingen.
