Tatsuya Tanaka (田中 達也, born June 9, 1992) is a Japanese football player who plays for Ratchaburi in Thai League 1.
Tanaka has previously played for Roasso Kumamoto, FC Gifu, Gamba Osaka, Oita Trinita, Urawa Reds, and Avispa Fukuoka.
While completing his university studies, he was a specially designated player for Roasso Kumamoto in the J2 League, making 4 appearances between 2011 and 2013.
He scored once in ten appearances in his first season as a professional but struggled to secure regular playing time.
Tanaka would not join Roasso in the J3 league, as his impressive performances as a wing-back caught the attention of J1 side Gamba Osaka, who added him to their squad ahead of the 2019 season.
