The 1897 Argentine Primera División was the 6th season of top-flight football in Argentina.[1] The championship was won by Lomas that achieved its 4th Argentine league title in 5 seasons. Lomas won the title after beating Lanús A.C. by 1-0 in a 3rd playoff match.[2]
The players of Lomas Academy (dissolved one year before) returned to its parent club, Lomas Athletic, while Lanús A.C., Banfield and Palermo A.C. made their debuts and Belgrano A.C. registered a "B" team to play the tournament.[3]

It finished 1–1 after extra time so a playoff was held four days later. As that match ended 0–0 with no modifications on the score during extra time, a second game was scheduled for September 19. The result was also a tie.
Finally, Lomas defeated Lanús 1–0 in the third match, becoming Primera División champion.[4]
