"Penso em ti, eu sei" (English translation: "Thinking of You, I Know") was the Portuguese entry in the Eurovision Song Contest 1985, performed in Portuguese by Adelaide.

The song is a ballad, with Adelaide telling her lover how she feels as their relationship comes to an end. The lyrics suggest that she will in fact end the relationship the moment the song ends, thus producing the conflicted emotions she feels.

The song was performed ninth on the night (following Belgium's Linda Lepomme with "Laat Me Nu Gaan" and preceding Germany's Wind with "Für Alle"). At the close of voting, it had received 9 points, placing 18th in a field of 19.

It was succeeded as Portuguese representative at the 1986 Contest by Dora with "Não Sejas Mau Para Mim".
