The team confirmed Ocon's signing today on a multi-year contract. A vacancy was created at Force India with Hulkenberg making a switch to Renault.
Ocon, who joined Manor Racing midway into this season replacing Indonesia Rio Haryanto, is also a Mercedes junior driver. The Silver Arrows have dominated F1 over the past three years and supplies engines to other teams on the grid including Force India.
Ocon said he is looking forward to his time at Force India, a team which is currently battling hard with Williams for fourth place in the standings.
"I am still relatively new to Formula 1, but spending half a season at Manor Racing has given me some valuable experience and I feel ready for this new opportunity with Sahara Force India.
"The next few months will be very busy as I do all I can to prepare for the challenge ahead of me. It means lots of days at the factory, working on the simulator and building relationships with the engineers and everybody in the team," he said.
"He is an exceptional talent, as his status as a Mercedes Junior demonstrates, and I have no doubt he will flourish inside our team. We have had our eye on Esteban for a number of years and have followed his progress through the junior categories where he delivered outstanding results," said Mallya.
"We ran him in the car last year during testing and his performance convinced us that he is more than capable of racing alongside Sergio," he added.
Ocon's best finish in seven starts has been 16th, which he managed on his debut in Belgium before finishing in the same spot in Malaysia.
