Montenegro isn't in the EU or the Schengen Area, so its rules for US tourists run separately from the Schengen countries covered elsewhere in this series — but the practical answer is the same: no visa needed for a normal tourist trip. Here's what's actually required, including a registration rule that's automatic if you're staying somewhere licensed. (For US citizens visiting for tourism; confirm current details at an official Montenegrin or US government source before you book.)

US passport holders can enter Montenegro visa-free for tourism for up to 90 days within a 180-day period, with no visa application or fee required in advance. Montenegro is an EU candidate country, among the more advanced in accession talks, but it isn't a member yet and isn't part of Schengen — so this is a separate visa-free arrangement, not the Schengen rule.
Your passport needs to be valid at the time of entry, with a blank page available for the entry stamp — Montenegro isn't part of the EU's biometric Entry/Exit System, so you'll still get a physical stamp here rather than the fingerprint/photo process now used in Schengen countries. As general good practice, carry a passport with a solid amount of validity left rather than cutting it close, even though Montenegro's own published guidance doesn't specify an exact months-beyond-stay buffer the way EU countries do.
Montenegro requires visitors to register their place of stay with local authorities. If you're staying at a hotel or a properly licensed accommodation provider, this is legally the property's responsibility and happens automatically — you don't need to do anything extra. If you're staying somewhere that isn't a registered accommodation provider, you're responsible for filing that registration yourself. For a normal hotel stay, this isn't something to worry about.
Only use Montenegro's official government domain, gov.me, for anything visa- or entry-related — a couple of sites styled as official Montenegrin e-visa portals showed up in search results during our research but couldn't be verified as genuine government domains, so treat anything outside gov.me with caution. Montenegro's EU accession is progressing but not close enough to change entry requirements in the near term, so the current visa-free rules aren't expected to shift soon — still, confirm the current terms before you book, since policy can change.
Entry rules change, and they depend on your nationality — always confirm the current requirements on the official government site before you book or apply. Only use official government (.gov) portals; ignore look-alike agency sites.
