Leše was attested in written sources in 1040 as silva que Leschahc nuncupator (and as predium Lêscah in 1050–63, and Loschach and Leschach in 1498). The name is derived from the plural demonym Lěščane, derived from the word lěska 'hazel'. The name thus originally means 'people living by the hazel grove'.
