| Monaco | Sovereign city-state | 2.02 km² | ~39,000 |
| Nauru | Sovereign island state | 21 km² | ~12,000 |
| Tuvalu | Sovereign island state | 26 km² | ~11,000 |
| San Marino | Sovereign republic | 61 km² | ~33,000 |

Note: Hum (Croatia) and similar micro-settlements claim "smallest town" but lack sovereign statehood. Vatican City is the smallest sovereign state universally recognized as such.
