Which has more of a party school vibe: University of Illinois at Urbana-Champaign or Miami University?

Miami University usually has more of the classic party-school feel. Its social scene is more centered on a traditional residential campus, Greek life is highly visible, and a lot of students describe weekends as revolving around house parties, bars, and a tight campus bubble in Oxford. UIUC is definitely social too, but the vibe is broader and less dominated by one type of nightlife.

For a student who wants a more contained, college-town scene where a lot of social life funnels into the same few routines and circles, Miami tends to feel more party-focused. Oxford is smaller and more self-contained, so student life often concentrates around campus and nearby off-campus housing. That can make the party culture feel more noticeable even if you are not personally participating in it.

UIUC fits the student who wants a big, active social environment without quite as much of that all-encompassing traditional party-school atmosphere. There are plenty of parties, bars, Big Ten energy, and Greek life, but the campus is larger and the student body is big enough that the social scene feels more spread out. At Illinois, it is easier to find people who are very into nightlife and people who barely engage with it at all.

If your question is specifically about which one feels more defined by partying as part of campus identity, Miami is the one that more often gets described that way. UIUC feels social and lively, but less like the entire student culture points in that direction.
