Myjava (Slovak pronunciation: [ˈmijaʋa]; historically also Miava, German: Miawa, Hungarian: Miava) is a town in Trenčín Region, Slovakia.

The settlement was established in 1533 and was colonized by two groups of inhabitants: refugees fleeing from the Ottomans in southern Upper Hungary (today mostly Slovakia) and inhabitants from north-western and northern Upper Hungary.

Today, the house of their meeting is now part of the Museum of the Slovak National Councils, a part of the Slovak National Museum network.

Before the establishment of independent Czechoslovakia in 1918, Myjava was part of Nyitra County within the Kingdom of Hungary.

On 8 April 1945, the Red Army dislodged the Wehrmacht from Myjava and it was once again part of Czechoslovakia.
