Plavi Horizonti (Serbian Cyrillic: Плави Хоризонти) is an urban neighborhood of Belgrade, the capital of Serbia.

Plavi Horizont is located in the western section of Zemun, stretching along the Belgrade-Novi Sad railway.

It borders the neighborhoods of Altina in the north and stretches into the direction of Vojni Put II and Kolonija Zmaj on the southeast and Zemun Polje on the northwest.

With the outbreak of the Yugoslav Wars in 1991, and especially after the 1995 Oluja offensive of the Croatian Army, many refugees settled in this area, which resulted in creation of several new settlements (Altina, Plavi Horizonti, Grmovac, Busije).

On 9 October 2023, a memorial was dedicated in the churchyard, commemorating citizens of Peć killed during the Kosovo war.
