The Spanish attacking midfielder had 23 goals and 17 assists for Sevilla in all competitions including Europa League qualifiers last season.
Media reports suggested that the signing may herald a move out by PSG's Brazilian star Neymar, who has been widely linked with a move back to Barcelona.
"We are delighted to announce Pablo Sarabia, the 27-year-old attacking midfielder from Sevilla, has signed a five-year contract with PSG," the Parisian club said in a statement.
