The 32-year-old LA Galaxy striker missed Friday night's 6-1 drubbing by Germany with an Achilles injury, but after training this morning, was included in the party which left Dublin for Torshavn.
However, fellow frontman Andy Keogh, who scored Ireland's consolation goal against the Germans, was not on the plane after suffering concussion following a collision in training yesterday.
A spokesman for the Football Association of Ireland said: "Following training this morning in Gannon Park, Robbie Keane has been ruled fit to travel with the squad for Tuesday's match against the Faroe Islands.
"Andy Keogh suffered a knock to the head in training on Saturday. He was observed overnight by the FAI medical team and has been ruled unfit to travel to the Faroe Islands this afternoon due to mild concussion."
