The Jihlava (Czech pronunciation: [ˈjɪɦlava] ^ⓘ ; German : Igel) is a river in the Czech Republic, a right tributary of the Svratka River. It flows through the Vysočina and South Moravian regions. It is 180.8 km (112.3 mi) long, making it the 8th longest river in the Czech Republic.

Etymology

The first written mention of Jihlava (written as Giglaue) is from 1226, when it was referred to when demarcating the boundaries of the properties of the Želiv monastery. ^[1] The origin of the name is often interpreted as coming from the German igel (i.e. 'hedgehog'), but a more likely origin is the Celtic word uig, meaning 'stream'. ^[2]
