FK Zeta is a football club from Montenegro. It is based in Golubovci, a suburb of Podgorica.

The club was formed in 1927 as FK Danica. In 1945 it was renamed to FK Napredak. In 1955 it was renamed to FK Zeta.

From the end of World War II until 1962 Zeta competed in the local Titograd municipal area league. That year they finally gained promotion to the provincial league of Montenegro where they played until 1996 when they qualified for competition at federal level in Second Federal League. Year 1996 was also significant because club was taken over by controversial businessman and former JSO paramilitary Radojica "Rajo" Božović who is still at Zeta's helm. In 2000, the club made its long-awaited final step forward, gaining promotion to the Yugoslav First Federal League.

Though still playing in the dilapidated Trešnjica Stadium, the club has made enormous strides from the days when it was basically a semi-professional side. Zeta finished the 2004/2005 season in third place in the First League of Serbia and Montenegro, just behind Belgrade powerhouses Partizan and Red Star. That success allowed the club to compete in UEFA Cup where it put in a decent showing.

Zeta (uppercase Ζ, lowercase ζ; Greek: ζήτα, classical [ˈdzɛːta] or [ˈzdɛːta] zḗta, Modern Greek: [ˈzita] zíta) is the sixth letter of the Greek alphabet. In the system of Greek numerals, it has a value of 7. It was derived from the Phoenician letter Zayin . Letters that arose from zeta include the Roman Z and Cyrillic З.

Unlike the other Greek letters, this letter did not take its name from the Phoenician letter from which it was derived; it was given a new name on the pattern of beta, eta and theta.

The word zeta is the ancestor of zed (UK) or zee (US), the name of the Latin letter Z. In other languages (e.g., Italian and Icelandic), the name zeta is used to refer to the Roman letter Z as well as the Greek letter.

The letter ζ represents the voiced alveolar fricative /z/ in Modern Greek.

The sound represented by zeta in Classical Greek is disputed. See Ancient Greek phonology and Pronunciation of Ancient Greek in teaching.

Most handbooks^[who?] agree on attributing to it the pronunciation [zd] (like Mazda), but some scholars believe that it was an affricate [dz] (like Italian zero). The modern pronunciation was, in all likelihood, established in the Hellenistic age and may have already been a common practice in Classical Attic; for example, it could count as one or two consonants metrically in Attic drama.
