The Haná is a river in the Czech Republic, a right tributary of the Morava River. It flows through the Olomouc, South Moravian and Zlín regions. It is formed by the confluence of the Velká Haná and Malá Haná streams. Together with the Velká Haná, which is its main source, the Haná is 57km (35miles) long. Without the Velká Haná, it is 35.3km (21.9miles) long.
The origin of the name is unknown. According to one theory, the name is derived from the Germanic word gana, meaning 'rich'.[1] Other theory says that the name is connected with the pre-Slavic word ganna that denotes a stony river, a river that brings stones.[2] The river gave the name to the ethnographic region of Haná.[3]

In a broader point of view, the Haná (as Velká Haná) originates in the territory of Drahany in the Drahany Highlands at an elevation of and flows to Kroměříž, where it enters the Morava River at an elevation of . It is 57km (35miles) long. Its drainage basin has an area of 607.8km2. The name Haná is used from the confluence of the Velká Haná with the Malá Haná in Vyškov and from this point to the confluence with the Morava, the river is 35.3km (21.9miles) long.[4] [5] The average discharge at its mouth is 1.7m3/s.[6]
