Osvaldo Ardiles Haay (born 1 May 1997) is an Indonesian professional footballer who plays as a left winger or forward.

Osvaldo Haay in 2016 at the age of 18 earned a spot in Persipura Jayapura's senior team that competed in the 2016 Indonesia Soccer Championship A.

He chose to play for Persebaya in the East Java provincial capital of Surabaya where he made 41 league appearances and scored 16 goals in two consecutive seasons.

Haay was part of the Indonesia under-23 national team that won silver in the 2019 Southeast Asian Games in the Philippines, in which he was the top goalscorer with eight goals.

Haay was raised in Jayapura, but he understands some Javanese language from his mother that became handy when the footballer played in Surabaya, East Java's capital.
