The 22-year-old has moved to the Addicks for an undisclosed fee after scoring 13 goals in 29 appearances during the last campaign.
Vetokele, who has won two international caps for Angola, has previously had spells in Belgium with Gent and Cercle Brugge.
The forward becomes Charlton's third signing of the summer, with Zak Ansah and Yoni Buyens having already made the move to the Championship outfit.
