The firm joins BDO International and Rabobank on the four-year programme which began his year.
Title rights and branding opportunities at all major FIH tournaments will be shared between the three partners, up to and including the Men's and Women's World Cups in 2006.
The programme has been established to allow a fourth and final partner to be added at a later date.
The announcement was made at the Rabobank Hockey Champions Trophy in Amsterdam.
Said FIH president Els van Breda Vriesman: "This is a huge step for the promotion of world hockey. Samsung's involvement as a global partner demonstrates hockey's ability to attract the backing of major multi-national organisations and, with Samsung's status as an Olympic Sponsor, also underlines hockey's strength as an Olympic sport.
"Revenue from the global partners' sponsorship will directly benefit host organisers of FIH major events and will also be used by FIH to improve the events' quality and profile, by enhancing spectator facilities, TV production and youth activities."
Electronics giant Samsung has joined the International Hockey Federation's band of global partners.
