Hohenzollern-Haigerloch was a small county in southwestern Germany. Its rulers belonged to the Swabian branch of the House of Hohenzollern. It became part of the neighboring Hohenzollern-Sigmaringen in 1767.

The more famous younger Franconian branch of the Hohenzollern family became Burgraves of Nuremberg, Margraves of Brandenburg, Kings of Prussia, and finally Emperors of Germany. Unlike their northern relatives, the Swabians remained Catholic.

The county of Hohenzollern-Haigerloch was created in 1576, when Karl I of Hohenzollern died and his lands were divided between his three sons:

• Eitel Friedrich IV of Hohenzollern-Hechingen (1545–1605)
• Charles II of Hohenzollern-Sigmaringen (1547–1606)
• Christoph of Hohenzollern-Haigerloch (1552–1592)

All three territories were located in south-western Germany and were fiefs of the Holy Roman Empire. The area is now part of the German Land of Baden-Württemberg. Hechingen, Sigmaringen, and Haigerloch were the capitals of the three states.

Per treaty, at the extinction of the line, the county reverted to the principality of Hohenzollern-Sigmaringen.

With the death of the last count, the county was permanently incorporated into the principality of Hohenzollern-Sigmaringen.
