Macháňová is a Czech surname, derived as the feminine form of Macháň. The name Macháň comes from the given name Mach, a Czech diminutive of Matěj, which itself is the Czech form of Matthias. In the New Testament, Matthias is the apostle chosen to replace Judas Iscariot (Acts 1:21-26). The root name Matthew ultimately derives from the Hebrew name Mattityahu, meaning 'gift of Yahweh'. While the root Matthias is associated with important historical figures such as Matthias I of Hungary, and Judas appears in the biblical context, Macháňová itself is less common and represents the typical Czech practice of adding the suffix "-ová" to form feminine surnames. It occurs predominantly in the Czech Republic.
