The top-seeded pair eased past the Romanian team of Irina-Camelia Begu and Monica Niculescu 6-2, 6-3 in the title clash.
"Title number 7 #SanTina @mhingis #WuhanOpen," the Indian star tweeted accompanied by a picture of the duo with the trophy.
Sania and Hingis had it relatively easy in the second round, quarterfinals and semi-finals after getting a first round bye in the tournament.
Sania and Hingis dropped serve three times and fought back from a 2-0 deficit in the second set to emerge triumphant in the summit clash today.
They have won their last three tournaments and their last 13 matches without dropping a single set.
They now head to the China Open in Beijing, where they have been given the top billing.
