Ernesto Federico Alterio Bacaicoa is an Argentine-Spanish film, theatre, and television actor. He is most known for his role in the Fernando Colomo films The Stolen Years and Havana Quartet, as well as for his role in the Argentine miniseries Vientos del agua. He is the son of Argentine actor Hector Alterio.

Vientos de agua is a 2006 Argentine- Spanish mini TV series created by Juan José Campanella. The drama traces a Spaniard's emigration to Argentina in the 1930s, and, years later, his son's immigration to modern-day Spain. Through this arc, the series explores "...the differences and similarities between the immigration of early last century Europeans to here and now there". Through this metaphor of immigration, the lives of individuals are compared and found to have more in common than their differences.
