Alejo & Valentina is an Argentine flash cartoon by Alejandro Szykula, created in 2002, aimed at teens and "adults with a childish mind". The animation style is very simplistic and the storylines are filled with nonsense humour, running gags and a random comedy tone. The main protagonists are Alejo and Valentina, characters based on the creator himself and his ex-girlfriend. Other characters include Carlitox and El Viejo.

It is currently being aired on MTV Latin America, with new episodes being broadcast weekly. The show is now in its fourth season.
