J. Erik Jonsson Central Library, Public library in downtown Dallas, United States.

J. Erik Jonsson Central Library is the main public library of Dallas, Texas, located in the heart of downtown. The building has ten floors in total, with eight above ground and two below, housing reading rooms, collections, and event spaces.

The library takes its name from J. Erik Jonsson, a co-founder of Texas Instruments who later became mayor of Dallas and led the campaign to fund and build the facility. His efforts turned what was a civic ambition into one of the city's main public spaces.

The library has a genealogy section where visitors can look up family records and historical documents. A dedicated fiber arts area sets it apart from most city libraries and draws people with an interest in textile crafts.

The building is easy to reach on foot from downtown Dallas and sits close to public transit stops. Because the collections are spread across several floors, checking the floor guide before your visit will save time.

The library's upper floors are angled away from Young Street, mirroring how the upper floors of Dallas City Hall across the open plaza face Marilla Street. The two buildings were designed as a pair, so the library turns its back on the street its entrance is on.
