The smallest countries ranked here use official total area, and free-association states are labelled rather than treated as silent United Nations members. Rank follows the 2025 World Factbook compilation of the ten smallest independent countries by official total area, in square kilometres [1]. In that official list the Holy See, Vatican City, is first, at 0.44 square kilometres, the outstanding official smallest independent country and the only one in the ten below one square kilometre [1]. Monaco is second, at 2 square kilometres in the Factbook rounding, while official and encyclopedia pages often give about 2.02 square kilometres, a slightly more precise official figure that this article labels rather than uses as a silent replacement [1][2]. Nauru is third, at 21 square kilometres, and Tuvalu is fourth, at 26 [1]. San Marino, at 61, Liechtenstein, at 160, and the Marshall Islands, at 181, complete the next three [1]. The eighth and ninth places in the same official Factbook ten are the Cook Islands, at 236 square kilometres, and Niue, at 260, both self-governing states in free association with New Zealand and not member states of the United Nations; this article keeps them in the Factbook ten and labels that political status rather than silently dropping them or silently treating them as United Nations members [1]. Saint Kitts and Nevis, at 261 square kilometres, is tenth in the same official list, and is a United Nations member [1].
A list limited to United Nations members plus the Holy See would, after the Marshall Islands, reach Saint Kitts and Nevis and then the Maldives and Malta, a different official-membership ten that this article labels rather than uses as a silent replacement [2]. The existing Finepedia list of smallest countries is Europe-only; this list is worldwide. The table is the official spine: one 2025 Factbook smallest-independent-countries compilation, free-association status labelled, and no unofficial Europe-only substitution is smuggled in as the worldwide fact.
Key Facts
The ten below are the 2025 Factbook smallest-independent-country leaders: the Holy See (Vatican City) 0.44 square kilometres, Monaco 2 (about 2.02 in more precise official pages), Nauru 21, Tuvalu 26, San Marino 61, Liechtenstein 160, the Marshall Islands 181, the Cook Islands 236, Niue 260, and Saint Kitts and Nevis 261 [1][2]. Rank 1 is the outstanding official total area, which is also the only country in the ten below one square kilometre.
The Maldives, at about 298 square kilometres, and Malta, at about 316, would enter a United Nations-members-plus-Holy-See ten after Saint Kitts and Nevis if the Cook Islands and Niue were set aside [2]. Those later names are labelled, not added as silent eleventh and twelfth Factbook ranks. A later official area revision will belong in a revision of a cell, not as an unlabelled change to the method.

1. Holy See (Vatican City)
The Holy See, Vatican City, has an official 2025 Factbook total area of 0.44 square kilometres, the smallest independent country in that compilation [1].

It is first as the outstanding official smallest independent country.

Conclusion
A 2026 smallest-countries list has to keep the 2025 Factbook spine: the Holy See at 0.44 square kilometres, Monaco at 2 square kilometres with a more precise official figure of about 2.02 labelled, and Nauru at 21, and it has to refuse to treat a Europe-only list, or a silent dropping of the Cook Islands and Niue, as a replacement for that official worldwide ten [1][2]. Tuvalu, San Marino, Liechtenstein, the Marshall Islands, the Cook Islands, Niue, and Saint Kitts and Nevis complete the same official ten, with free-association status labelled and the Maldives and Malta noted as the next United Nations-member names [1][2]. The useful habit is one official total-area compilation, one labelled political status, and a refusal to mix an exclusive economic zone into a land-area rank.
A later official area revision will belong in a revision of a cell; it will not change the method. Those labelled official areas are the spine of the list, and they will still be the spine after a later yearbook has restated a total in a later year.
