Feria starts on April 23

Argentina’s Feria Internacional del Libro de Buenos Aires will open on April 23, 2026, and run through May 11 at La Rural in Palermo. (feriadellibro.ar) The official fair site lists the opening ceremony for April 23 at 6 p.m. and names Argentine writers Gabriela Cabezón Cámara, Selva Almada and Leila Guerriero as the invited speakers. (feriadellibro.ar) Peru is the guest country of honor for the 2026 edition, according to the organizers, Fundación El Libro, the nonprofit that runs the fair. (feriadellibro.ar, feriadellibro.ar) The 2026 fair is being billed as the event’s 50th year, with more than 45,000 square meters dedicated to books and cultural programming. (feriadellibro.ar, buenosaires.gob.ar) April 23 is also World Book and Copyright Day, the annual United Nations and United Nations Educational, Scientific and Cultural Organization observance for books, authors and reading. (unesco.org, un.org) That date is fixed on the international calendar every year, and UNESCO ties it to a global campaign around reading, publishing and copyright. In 2026, UNESCO says Rabat is the designated World Book Capital. (unesco.org) For Buenos Aires, the calendar choice links a major commercial and cultural fair to a day already associated worldwide with reading. The city’s tourism office describes the fair as the most attended publishing and literary event in the Spanish-speaking world. (unesco.org, buenosaires.gob.ar) The public schedule also shows weekday hours from 2 p.m. to 10 p.m. and weekend and holiday hours from 1 p.m. to 10 p.m. The city says “La Noche de la Feria” is set for April 25, with free admission starting at 8 p.m. (buenosaires.gob.ar) Before the public opening, the fair’s professional program is scheduled for April 20 to 24, with meetings aimed at rights sales and publishing business. Organizers say the program includes international editors and agents. (feriadellibro.ar) The result is a fair that starts on a symbolic date, opens with three of Argentina’s best-known writers, and folds its 50-year celebration into a global day for books.
