Czech and Slovak (Leško): from a pet form of the personal name Aleš (see Ales). Polish (Leśko): from a variant of the personal name Leszko, a pet form of Lech. In North America, this surname may also be an altered form of the variant Leszko, which is also a Rusyn (Lemko) name; compare Leshko.

Hungarian (Leskó): probably from an old Hungarian personal name Leskó derived from the Ugric word les ‘look’ or ‘peek’. Alternatively, in some cases, a surname of Slovak origin (see 1 above).
