The Cuban newspaper Granma said Castro was to meet with Algerian President Abdelaziz Bouteflika and other government officials.
Castro just finished up a three-day visit to Angola where he met with President Jose Eduardo dos Santos and other top officials from the ruling Movement for the Liberation of Angola and Cuban workers, Prensa Latina reported.
He also paid tribute to the party's late revolutionary leader Agostinho Neto, and top Cuban military officer Raul Diaz Arguelles, who died while fighting for Angola's independence.
Castro and dos Santos also witnessed the signature of several cooperative agreements between the two nations. Castro spoke at a special session of the Angolan National Assembly and toured an industrial park outside Luanda.
