Split city derby (Croatian: Splitski gradski derbi) or Derby of St. Duje (town's patron saint) is the name given to matches between Hajduk and RNK, two clubs from the Adriatic city of Split. The teams are supported by their fanbases called Hajduk's Torcida and Split's Crveni đavoli. Games are played on two nearby stadiums, Poljud and Park Mladeži.

Derby between Hajduk and Split dates back to the days of Kingdom of Yugoslavia in the early 1920s after clubs were founded only one year apart. The first match between the two was an exhibition on 16 Mar 1919 between Hajduk and Anarh, ending in 11-0 Hajduk win. While today's RNK Split was in those times often dissolved, renamed or joined with other Split teams (over the years team was called Anarh, JNSK Jug, Split ŠK, Borac BŠK, HAŠK Split, Vicko Krstulović, Arsenal) Hajduk maintained its name and home ground, providing a field for their matches until Park mladeži was built in 1955. Teams regularly met during this period, playing friendly games and Split Championship. Between 1920 and 1941, clubs played 24 official and close to 50 friendly matches, with Hajduk winning almost all of them.

Following the end of World War II, both clubs were dissolved and joined anti-fascist movements. Split players were also active soldiers during the Spanish Civil War. After the war ended, both were reactivated, and continued their tradition which now spans to over 100 friendly games. First official league meeting came after Split qualified for their first league appearance in 1957–58 season. Split won a home game 2-0, but was eventually eliminated, only to return three years later for one more season. Their managers at time were one of Hajduk's greats Luka Kaliterna and Frane Matošić.^[1] Before Yugoslavia fell apart teams met in Yugoslav Cup couple of times, with Hajduk winning every game and achieving far memorable results.

Since Croatian independence, Hajduk joined Croatia’s top tier, while Split played lower divisions. Teams met in 1992–93 Croatian Cup in a surprising 3-0 Split win at Poljud, only to see Hajduk winning 2nd game 4-0 and go to the next round. For the next 18 years, only friendlies were occasionally played before Split earned their first elite division promotion for 2010–11 season. In the last few years, Hajduk went through financial and organisational changes, and with Split playing their best football in recent history, derbies became more leveled than ever before. Today, Split is going through a financial crisis while Hajduk became more stabilised but in the derbies, they are still equally matched.

The most recent derby was played on 31 July 2016 in Park Mladeži, in the 29th round of the 2016–17 Prva HNL season. It ended in a 1–0 Hajduk's win, with Franck Ohandza's only scorer.^[2]
