Vinko Knežević or Vincent Knesevich of Saint Helen (Croatian: Vinko Knežević od Svete Jelene, Hungarian: Vince Knezsevics de Szent-Ilona); 30 November 1755 – 11 March 1832) was a Croatian nobleman and general in the Habsburg monarchy imperial army service.

He commanded an infantry brigade at Marengo the following year and led Austrian Empire troops in the Tyrol in 1805 and at Graz in 1809.

Near Vaprio d'Adda, the Palatine Hussars launched three attacks and finally broke through Paul Grenier's division, inflicting 200 casualties and capturing 300 French soldiers outright.

Together with other Austrian and Russian units, they rounded up 2,800 prisoners and collected as trophies 12 cannons, one howitzer, six ammunition wagons, and one standard.

On 28 April, his regiment was part of the force that trapped Jean-Mathieu-Philibert Serurier's division and compelled it to surrender.

[7] From 16 November to 3 December, he and his hussars participated in the siege of Cuneo under the command of Johann I Joseph, Prince of Liechtenstein.

[1] However, another source shows that he commanded a brigade with the rank of General-major in Konrad Valentin von Kaim's 4,939-man division at the Battle of Marengo on 14 June 1800.

[9] During the late morning, Kaim's division repeatedly attacked the French line behind Fontanone Creek with little success.

[10] Later in the day, all three brigades of Kaim's division joined the pursuit under Anton von Zach and were involved in the rout of the main column at the end of the battle.

[1] At Strub Pass, the Austrians defeated Bavarians under Bernhard Erasmus von Deroy and at Sharnitz repulsed French VI Corps troops.

However, at Leutasch, the French wiped out 936 Austrians, enabling Marshal Michel Ney's troops to occupy Innsbruck.

[1] Knežević was given command of the 3rd Division in Ignaz Gyulai's IX Armeekorps at the outbreak of the War of the Fifth Coalition.

[14] However, the corps structure was immediately changed so that 10,000 troops under Johann Gabriel Chasteler de Courcelles could be sent to support the Tyrolean Rebellion.
