Horný Vadičov (Hungarian: Felsővadas) is a village and municipality in the Kysucké Nové Mesto District in the Žilina Region of northern Slovakia.

Due to the village's ancient history, it is difficult to determine exactly when modern Horný Vadičov was established.

[4] The village at that time was populated by the Lusatian people, denoted by multiple sites discovered proving their existence here.

[3] Beginning after the 12th century, the Vadičov valley, where the village is located today, belonged to the royal estates of Starhrad (Varín Castle[5]).

Documents specifically detailing the land of today's Horný Vadičov begin in 1494 when a transfer of ownership of the village, referred to as "Villa Vadycho", from Mikuláš to his now of–age son Martin takes place.

In the first decades of the 16th century, other Horváth family members acquired part of the Vadič estate, including today's Horný Vadičov.

[6] In response to the 2022 Russian Invasion of Ukraine, Slovakia as a nation, including Horný Vadičov, welcomes the arrival of Ukrainian refugees from war.

[9] Horný Vadičov is a municipality whose representative of the village on a national level and highest executive body is the mayor, who has legislative authority in the town, along with the General Assembly and Chief Inspector.

[10] Being a smaller village surrounded by mountains, Horný Vadičov has a high tourist appeal, especially in skiing in the winter.
