Rivalries
An 2000s survey found that Fenerbahçe supporters only see the Istanbul giants as their rivals and most dislike Galatasaray, followed by Trabzonspor and Beşiktaş, although all of Galatasaray, Beşiktaş, and Trabzonspor fans see Fenerbahçe as their main rival, mostly due to Fenerbahçe by itself dominating Turkish football for many years in the past.

Fenerbahçe-Galatasaray rivalry 
Fenerbahçe's longest-running and deepest rivalry is with their nearest major neighbours, Galatasaray, with matches between the two being referred to as Intercontinental derby, also known as "the derby of immense and never ending hate". In an interview, a Fenerbahçe fan stated "I'd prefer dying honorfully and meeting my creator to living as a Galatasaray fan. Actually, I'd prefer going to hell over being a Galatasaray fan" while a Galatasaray fan stated "My hate for Fenerbahçe is more than any feeling I ever had. If Fenerbahçe was a person, I'd murder him". The derby is very popular, and during the derby hours traffic in Turkey is significantly relaxed as most are at their home watching, and the hate between the two clubs Fenerbahçe and Galatasaray has reached such a level that many fans of both clubs have died from heart attack after their clubs have lost the derby. Both Fenerbahçe and Galatasaray also have a global following, Galatasaray is more popular in Europe and the United States, and Fenerbahçe is more popular in Muslim majority countries and the United Kingdom.

The rivalry, previously named "the derby of friendship", has turned into a derby of hate on 23 February 1934, when a friendly game between both clubs turned into a riot, forcing the match to be abandoned. The rivalry has led to violence among supporters on numerous occasions. Torches, smoke, flags, and giant posters are used to create visual grandeur and apply psychological pressure on visiting teams, which fans call "welcoming them to hell".

Other rivalries 
Matches against Beşiktaş are also derbies, but the rivalry is not as intense and fierce as that between Fenerbahçe SK and Galatasaray SK. These derbies are referred to as the "friendly derby". In addition, Fenerbahçe and Trabzonspor have had a strong on-pitch rivalry in the late 1970s, which has, although not so much on the pitch anymore, continued in recent years off the pitch with hate among fanbases growing rapidly especially after 2011.

Friendships with other clubs 

Fenerbahçe has had friendly relations with clubs from different countries, due to many reasons. Some include: in Turkey, Kırklarelispor, Menemenspor, Eskişehir Demirspor, Ankara Demirspor, Eskişehirspor and many more; in Brazil, Coritiba; in Serbia, Novi Pazar; in Norway: Lillestrøm, in Greece; AEK and; in England, Sheffield United; in the Netherlands, Feyenoord; in Germany: Bayern Munich. In addition to this, Fenerbahçe, Beşiktaş and Galatasaray were officially brother clubs in the 1910s, due to the fact that their common goal was to defeat non-Muslim teams. This, however, is no longer the case.

In November 2011, Fenerbahçe's GFB created a friendly relationship with Serbian club FK Novi Pazar's supporter group Torcida Sandžak. During a Turkish Super League match against İstanbul Büyükşehir Belediyespor at the Şükrü Saracoğlu Stadium, the GFB and 1907 Gençlik stands deployed a giant banner reading "Kalbimiz Seninle Novi Pazar" ("Novi Pazar, Our Hearts Are With You").  Eventually, in the match against Radnički Kragujevac in the Serbian SuperLiga, Torcida Sandžak members deployed a banner reading "Sancak'ta atıyor, Fenerbahçe'nin kalbi" ("The heart of Fenerbahçe beats in Sandžak").

On March 2, 2012, Fenerbahçe's GFB and 1907 Gençlik group members were invited to Novi Pazar for the match against Partizan in the Serbian SuperLiga. Thousands of Torcida Sandžak members welcomed GFB and 1907 Gençlik's 17 members.

There is an informal friendship and fraternization between the fans of AEK and Fenerbahçe. In the 2017 Euroleague final, Fenerbahçe S.K. supporters displayed a banner which read "Same City's Sons"
