The seventh-seeded Bouchard was the only woman to reach the semifinals at the year's first three Grand Slam tournaments. She lost in that round at the Australian Open and French Open, before her run at the All England Club made her the first Canadian tennis player to reach a major final.
Bouchard made her U.S. Open debut in 2013, exiting in the second round.
To get to the fourth round this year, she will need to beat 30th-seeded Barbora Zahlavova Strycova.
If Bouchard makes it to the quarterfinals, she could face No. 3 Petra Kvitova in a rematch of the Wimbledon final.
