Sajlovo (Serbian Cyrillic: Сајлово; Hungarian: Zajol) or Donje Sajlovo (Serbian Cyrillic: Доње Сајлово) is a neighborhood of the city of Novi Sad, Serbia.

Settlements were named after monk Isaija from nearby monastery that existed in the 12th century in the east of Rumenka.

Name Sajlovo/Isailovo is of Slavic origin, which indicate that these settlements were initially inhabited by Slavs.

Modern settlement of Sajlovo was mostly settled during the 1990s with Serb refugees from parts of former Yugoslavia.

The neighbouring city quarters are Jugovićevo in the south-east, and Industrijska Zona Jug in the north-east.
