The three-year deal commences following the completion of the 2009/10 football season. The new Sponsorship package gives Samsung additional rights.
The deal was unveiled by the club and its principal partner today at Chelsea FC's training base in Cobham.
Samsung has been a sponsor of the premiership club since 2005 when it agreed a deal worth an estimated £55m over five years.
Chelsea FC CEO Peter Kenyon decline to comment on the financial investment but said the deal would mutually benefit both club and sponsor.
Last month premiership rival Manchester United also signed a lucrative sponsorship deal with US finance brand Aon.
