Adalbert Mikhailovich Erdeli (Ерделі, Адальберт, also seen as Erdely, born Béla Erdélyi; May 25, 1891 - September 19, 1955) was a Subcarpathian painter, one of the main figures of midcentury Transcarpathian art. Erdeli was born in Hátmeg, Austria-Hungary (today Zahattia in Ukraine). He studied at the Budapest Academy of Arts from 1911 through 1915, then taught in Mukačevo (now Mukachevo, Ukraine) and Užhorod (now Uzhhorod, Ukraine), when Transcarpathia already became part of Czechoslovakia. Among his students was Fedir Manailo. He died in Uzhhorod.
