School 2017 (Korean: 학교 2017; Hanja: 學校 2017; RR: Hakgyo 2017) is a South Korean television series starring Kim Jung-hyun, Kim Se-jeong, Jang Dong-yoon, Han Sun-hwa, and Han Joo-wan. It aired on KBS2 from July 17 to September 5, 2017 every Monday and Tuesday at 22:00 (KST) for 16 episodes. The series is the seventh installment of KBS2's School franchise.

The plot follows a class of high school students attempting to overcome the stress of being ranked by their exam grades, and facing the difficulties of being a teenager in a high-pressure, corrupt system. Its central protagonist is Ra Eun-ho (Kim Se-jeong), a cheerful and kind-hearted 18-year-old who dreams of being a webtoon artist but is caught up in the search for a mysterious troublemaker in the school, known as 'Student X'. When she is accused of being Student X, her dream of going to university to study art is put at risk as she faces expulsion. Hyun Tae-woon (Kim Jung-hyun) is the son of the director of the school who enjoys his youth but hides deep scars. Song Dae-hwi (Jang Dong-yoon) is a bright student who's ranked 1st every time but doesn't have enough money for his dream college.

In May 2017, KBS offered the leading role to Kim Yoo-jung as a follow-up project to her popular series Love in the Moonlight (2016). By June 2017, she officially declined.

The first script reading of the series took place on June 19, 2017 at the KBS Annex Building in Yeouido, Seoul, South Korea.
