Caterham team principal Cyril Abiteboul has confirmed that Charles Pic has left the team.
Pic raced for Caterham in 2013 and originally joined them on a multi-year deal.
Pic made his Formula 1 debut for Marussia in 2012 before switching to Caterham in 2013.
"Charles, unfortunately will not be with us next year," Abiteboul told French media outlet Infosport+.
"It is unfortunate that the partnership between Caterham and Charles ends."
"However, personally, I want to thank Charles for the job he has done last year. "
Caterham is close to announcing their 2014 line-up, with Kamui Kobayashi strongly linked with a Formula 1 return.
GP2 racer Marcus Ericsson is tipped to join the team, with 2013 driver Giedo van der Garde's sponsors having been removed from Caterham's website.
