Ostapenko's exit means that Angelique Kerber and Maria Sharapova - who play each other on Saturday - are the only two Grand Slam champions remaining in the women's draw.
There were 11 double faults in a scrappy affair on Margaret Court Arena, with Latvia's Ostapenko losing all five of her service games in the first set.
Ostapenko took a medical timeout before the second set for treatment on her thigh and she found enough rhythm to take the game into a third set.
Despite some solid defence from Ostapenko, Kontaveit got the decisive break before winning eight of the final 10 points of the match to claim victory.
