The 2017 Pittsburgh Pirates season was the franchise's 136th season overall, 131st season as a member of the National League, and the 17th season at PNC Park. They failed to improve on their record from the previous season and finished fourth in the National League Central. The Pirates failed to qualify for the playoffs for the second consecutive season.

Offseason and spring training Infielder Jung-ho Kang was found guilty by a South Korean court for his third offense of driving under the influence, and as a result, the initial request for a work visa to enter the United States for the 2017 season was denied. He would miss the whole season with the Pirates.

The Pirates recorded a 19–12 win–loss record in preseason spring training, the third best record in the Grapefruit League. In addition, two of their games finished tied and were therefore not included in the standings.

Regular season April April 3 – The Pirates lost on Opening Day to the Boston Red Sox 5–3. April 7 – In their home opener against the Atlanta Braves, the Pirates defeated the Braves 5–4.
