Foran will join the Titans for seasons 2023 and 2024 and add experience and depth to the youthful Titans spine.
Foran has played 246 NRL games, primarily for the Manly Sea Eagles, and won two Premierships across two stints with the club.
Known for his strong running game and slick ballplaying, Foran has been among the top echelon of five-eighths since his debut in 2009.
Titans Head Coach Justin Holbrook said Foran will add another element to his young side.
