Knihovna Jiřího Mahena, Public municipal library in Brno, Czech Republic.

Knihovna Jiřího Mahena is Brno's city public library, the second largest municipal library in the Czech Republic, with its central library in the Baroque Schrattenbach Palace on Kobližná Street and 34 branches across the city. Two detached workplaces belong to the central library: the IN-centrum in the Klein Palace and the Mahen Memorial in the Masaryk district.

The library was founded in 1921 as Brno's public reading institution. Its relocation to the Schrattenbach Palace in 1950 marked a significant moment, establishing its current home in this Baroque building.

The library honors its namesake, Jiří Mahen, Brno's founding librarian whose vision shaped the institution's direction. Visitors can explore the memorial space dedicated to his life and professional contributions to the city's cultural development.

The library provides comfortable spaces for study, reading, and research within the historic palace. Different sections are organized by material type, and visiting during daytime hours on weekdays offers the most comprehensive access to resources and staff assistance.

The library's branches joined the automated network gradually: the Mahen Memorial and Bystrc branches were the first, in 2002, and public internet access arrived at the branches only after that year. The central library on Kobližná had offered internet to the public since 1997.
