Aleksander Šeliga (born 1 February 1980) is a Slovenian retired footballer who played as a goalkeeper.

Šeliga played most of his career for hometown club Celje in the Slovenian PrvaLiga.

In 2005, he joined Slavia Prague, but after an unsuccessful period with the Czech side, he returned to Celje.

The club also needed a keeper, after Cássio Ramos returned to PSV Eindhoven after an ended loan-period.

Šeliga earned his only appearance for the senior Slovenian national team on 3 March 2010, after taking the field as a substitute in an international friendly against Qatar in Maribor, which Slovenia had subsequently won 4–1.
