Ostrovo (Serbian Cyrillic: Острово, Hungarian: Lászlófalva) is a village located in the Municipality of Markušica, within Vukovar-Syrmia County, eastern Croatia. Situated on the borderlands between historical regions of Slavonia and Syrmia, it spans an area of 16.3 km² and had a population of 408 as of the 2021 census.

Historically, Ostrovo has been inhabited since prehistoric times, with archaeological evidence pointing to Iron Age settlements. During the Middle Ages, the village was part of Valkó County and later came under Ottoman control. Following the Treaty of Karlowitz in 1699, the village was incorporated into the Habsburg Monarchy. Ostrovo was strongly affected by both World War II and the Croatian War of Independence. During the former, the village endured occupation and the deportation of residents to the Jasenovac concentration camp. In the latter, it was part of the self-proclaimed Serb entity of SAO Eastern Slavonia, Baranja and Western Syrmia before being peacefully reintegrated into Croatia under UNTAES administration after the signing of the 1995 Erdut Agreement.

Today, Ostrovo is a rural settlement with a predominantly Serb population.
