Valverde, who helped Barca win the UEFA Cup Winners' Cup and Copa del Rey during his two-year spell at the club, had impressed since taking charge of Athletic for a second time in 2013.
He led the club to four successive top-seven finishes, a Copa del Rey final and the quarterfinals of the Europa League.
The former Espanyol, Olympiakos, Villarreal and Valencia boss also helped Athletic lift their first silverware in three decades when he masterminded a 5-1 aggregate defeat of Barca to win the 2015 Spanish Super Cup.
Barca will unveil their new boss next week, with Enrique leaving the post following this weekend's Copa del Rey final against Alaves.
Former player Enrique, 47, took charge in 2014 and has so far led Barca to eight titles, including back-to-back league and cup doubles in his first two years as well as the 2015 Champions League.
Barca assistant manager Juan Carlos Unzue, Everton boss Ronald Koeman, former Paris Saint-Germain coach Laurent Blanc and Oscar Garcia of Red Bull Salzburg have also been linked, while in recent weeks other potential candidates including Jorge Sampaoli, Diego Simeone and Mauricio Pochettino have ruled themselves out.
