Still due to her Achilles problem, Vlašić only made one appearance in the 2016 season in Split on January 29 where she took the win with 1.95 m, jumping over the qualifying standard (1.93 m) for the 2016 Summer Olympics. On 3 February, she had surgery in Turku, Finland. Despite having not competed during the outdoor season (she cancelled her participation at the European Championships and in the London Diamond League), she was selected by the Croatian Federation alongside Ana Šimić to represent Croatia in the high jump at the Olympics.
