36, or about 37, depending on who is counting
Vermeer left a small oeuvre, and the museums that hold it do not print one number. On its artist page the Mauritshuis says we know of only 36 paintings by him. The same museum's press release for the Google Arts and Culture project repeats that 36, and adds the geography: 18 collections, seven countries, in Europe and the United States. The release says a single real-world exhibition of every painting cannot happen, because some canvases are too fragile to travel and some museums will not lend.
The Rijksmuseum, announcing the 2023 Amsterdam exhibition, used a wider figure: approximately 37 paintings attributed to him, of which at least 27 were in the show. The exhibition FAQ then prints a numbered checklist that runs to 28 titles. Twenty-seven and twenty-eight are both on that site. This page reports both and does not average them.
English Wikipedia's list (checked 2026-10-29) says 34 paintings are firmly attributed, with question marks over a further three, against the 74 pictures Théophile Thoré-Bürger gave him in 1866. The shrinkage is part of the story. Vermeer has been widely forged, and many of those extra names have been taken off the list. No drawings or preparatory paintings are known, according to the same article.
A count with this much disagreement is still usable if each number stays attached to the institution that printed it. The method is the same one used for where Monet's paintings are: say which list, say the date it was read, and say what the list is not.
The one that is not on a wall
The Mauritshuis press release names The Concert (about 1664) inside the set of 36, and says it was stolen from the Isabella Stewart Gardner Museum in Boston in 1990 and never recovered. It is in the virtual museum because a photograph exists. It is not in the 2023 Amsterdam checklist, because there was nothing to lend.
English Wikipedia's article on the Gardner theft (checked 2026-10-29) is the public summary of that night: two men admitted in the early hours of 18 March 1990, thirteen works taken, The Concert among them. The museum's theft page is the institutional record. Nothing read for this guide reports a recovery.
The Concert is inside the Mauritshuis count of 36, and it is the one a visitor cannot stand in front of.
Where the 2023 exhibition list puts the others
The rows below are counted from the Rijksmuseum FAQ checklist for the 2023 exhibition (the numbered list of 28), not from a fresh survey of every museum database. A painting can be by Vermeer, in the Mauritshuis's 36, and still be absent here if it did not travel to Amsterdam. Kenwood House and the Royal Collection appear on the Mauritshuis partner list for the virtual museum and are not given individual titles on the FAQ page used here, so they are left off the table.
| Holder, as named on the FAQ list | Works on that list | Count |
|---|---|---|
| Rijksmuseum, Amsterdam | The Milkmaid; The Love Letter; View of Houses in Delft (The Little Street); Woman in Blue Reading a Letter | 4 |
| Mauritshuis, The Hague | Girl with a Pearl Earring; View of Delft; Diana and Her Nymphs | 3 |
| Frick Collection, New York | Girl Interrupted at Her Music; Mistress and Maid; Officer and Laughing Girl | 3 |
| National Gallery of Art, Washington | A Lady Writing; Girl with a Flute; Girl with the Red Hat; Woman Holding a Balance | 4 |
| Metropolitan Museum of Art, New York | Allegory of the Catholic Faith; Young Woman with a Lute | 2 |
| Gemäldegalerie Alte Meister, Dresden | Girl Reading a Letter at an Open Window; The Procuress | 2 |
| Gemäldegalerie, Berlin | The Glass of Wine; Woman with a Pearl Necklace | 2 |
| National Gallery, London | A Young Woman seated at a Virginal; A Young Woman standing at a Virginal | 2 |
| Musée du Louvre, Paris | The Lacemaker | 1 |
| National Galleries of Scotland, Edinburgh | Christ in the House of Mary and Martha | 1 |
| Städel Museum, Frankfurt | The Geographer | 1 |
| National Gallery of Ireland, Dublin | Woman Writing a Letter, with her Maid | 1 |
| Leiden Collection, New York | Young Woman Seated at a Virginal | 1 |
| Kufu Company, on loan to the National Museum of Western Art, Tokyo | Saint Praxedis | 1 |
Those 28 titles are the FAQ list. They are not a claim that Washington and Amsterdam own the same number of Vermeers in every catalogue. Girl with a Flute and Girl with the Red Hat have both been argued over, which is one reason the Rijksmuseum's "about 37 attributed" and the Mauritshuis's "only 36" can differ by a canvas or two without either museum miscounting a wall.
The Milkmaid (Rijksmuseum SK-A-2344) is the picture at the top of this page. What the 2022 scans found under the paint, and what the 1696 sale price was, is on Vermeer's Milkmaid. Girl with a Pearl Earring is at the Mauritshuis. The famous-paintings page records the museum's own line that it is a tronie, a character study, not a commissioned portrait.
What a visitor can actually do with the list
For a single city, Amsterdam and The Hague are the short trip: four works on the FAQ list at the Rijksmuseum, three at the Mauritshuis, seven pictures a train ride apart. New York's Frick and Met account for five more on that same list, with the Leiden Collection as a sixth New York holder and Washington's National Gallery of Art as four. Paris, on this checklist, is one painting, The Lacemaker.
The Mauritshuis press release's seven countries and 18 collections are the wider map, and they include the Gardner, where the missing Concert is the reason one stop is an empty frame. Borderline attributions, Saint Praxedis and the small Washington tronies among them, move the total between 34 and 37 depending on the scholar. The useful check is the object page of the museum named in the row, not a round number in a caption.
