南斯拉夫情结（塞尔维亚-克罗地亚语：jugonostalgija / југоносталгија）是存在于前南斯拉夫诸国部分人之间的一种情结，主要指这些人怀念前南斯拉夫的感情。对南斯拉夫情结有肯定和否定两种看法。肯定者认为南斯拉夫解体后的各国广泛存在排他的民族主义，并且经济混乱，贫富不均。而否定者则认为对南斯拉夫的怀念意味着对新国家的否定。现在南斯拉夫情结主要体现在文化领域，但在政治上，支持恢复南斯拉夫的人已所剩无几。随着塞蒙解体，现在世界上已无国家使用南斯拉夫为国名。而认为自己是南斯拉夫人的民众也大幅减少。

Yugo-nostalgia is a little-studied psychological and cultural phenomenon occurring among citizens of the former Socialist Federal Republic of Yugoslavia (SFRY). While its anthropological and sociological aspects have not been clearly recognized, the term, and the corresponding epithet "Yugo-nostalgic", is commonly used by the people in the region in two distinct ways: as a positive personal descriptive, and as a derogatory label.
