T. B. Blackstone Memorial Library is a building that is part of the Chicago Public Library System and is named after Timothy Blackstone. The building was designed by Chicago architect Solon S. Beman. It is now known as the Chicago Public Library – Blackstone Branch and commonly referred to as Blackstone Library, or Blackstone Branch and sometimes Blackstone for short. The Concord Granite building's two-year construction started in 1902, and it was dedicated on January 8, 1904. Blackstone Library marks the beginning of the Chicago Branch Library System as the first dedicated branch in the system. Blackstone is also the only branch of the 79-branch Chicago Public Library branch system that was constructed using private funding.

The building is located in Chicago's Kenwood community area in Cook County, Illinois, United States and serves the Hyde Park, Kenwood, and Oakland community areas. The branch celebrated its 100th anniversary of service in 2004. Today, the library has bronze and mahogony furnishings and has themed paintings on the rotunda ceiling. The library is equipped with custom-designed furniture and makes public Wi-Fi access available to its patrons.

The library was dedicated to the memory of Timothy Beach Blackstone, President of the Chicago and Alton Railroad from 1864 to 1899, a period longer than any of his contemporaries. Blackstone, who had died on May 26, 1900, was also the founding president of the . He had owned the property on which the Blackstone Library now stands, and he donated this tract for the construction of the library after his death. The library was built on the tract through a codicil in his will, carried out by his wife, Isabella Norton Blackstone (1838–1928), after his death. Blackstone Library was his contribution to the city where he had made his fortune and stands as a monument to his generosity. Blackstone is 13,794 sq ft (1,281.5 m²) and its original cost was $250,000 ($7,071,154 today).
