Old Dallas Central Library, Civic building and library in downtown Dallas, United States.

The Old Dallas Central Library is a multi-level civic building at 1954 Commerce Street in downtown Dallas, designed by architect George Dahl as the city's public library. It has four above-ground levels and two basements, with 120,000 square feet of floor space and provisions for two additional floors. The facade once held Marshall Fredericks's 20-foot aluminum relief "Youth in the Hands of God."

The building opened in 1955 to replace an earlier library that had served the growing city. It remained the main library for the community until collections were moved to a new central facility in 1982.

The building's 1955 opening was marked by a public dispute over Harry Bertoia's abstract metal screen above the circulation desk: Mayor R.L. Thornton called it "a bunch of junk painted up," and architect George Dahl bought the work himself until citizens donated money to reinstall it. The screen now hangs in the J. Erik Jonsson Central Library.

The building stands at 1954 Commerce Street, on the edge of the Farmers Market District beside Main Street Garden Park. It has been vacant since the library left in 1982; the Dallas Morning News moved its headquarters here in December 2017 after a lengthy redevelopment. The former auditorium in the second basement seated 250 people.

The building holds an auditorium that seats around 250 people for public events and gatherings. An outdoor terrace complements this space and provides another spot where people can meet and spend time together.
