The Danish teenager, who triumphed in Ponte Vedra, Florida last week, reached the semi-finals with a 6-3 6-4 win over sixth-seeded Russian Nadia Petrova after former world number one Jankovic lost 1-6 6-3 6-3 to Slovak Daniela Hantuchova.
Hantuchova, who had not beaten the second-seeded Serb since 2006, broke serve six times in a match that took two hours and 18 minutes on the green clay of the stadium court.
Wozniacki, who lost in last year's final to German Sabine Lisicki, enjoyed her second win over Petrova in a month after toppling the Russian in the fourth round at Indian Wells.
Wozniacki will face Vera Zvonareva after the Russian seventh seed beat Melanie Oudin of the United States 7-5 6-2.
The week's other WTA event in Barcelona will have an all-Italian final after Francesca Schiavone beat Kazakhstan's Yaroslava Shvedova 6-1 6-2 and Roberta Vinci beat Romania's Alexandra Dulgheru 6-7(4) 6-1 6-2 in the semi-finals.
