The incumbent on the account, which covers PCs, laptops and handheld computers, was McCann Erickson.
The win consolidates Publicis' relationship with HP in Europe following its retention of the EMEA direct marketing account last May.
The pitch is likely to have been contested by BBDO, which handles some HP regional work.
Publicis Groupe's pitch was co-led by Richard Pinder, chief operating officer at Publicis Worldwide and Pedro Simko, chairman of Saatchi & Saatchi Geneva and EMEA chief marketing officer.
Pinder said: "HP is an extremely long-standing and highly valued client and we are delighted to be expanding our relationship across our home territories."
