Osaka Prefectural Nakanoshima Library (大阪府立中之島図書館, Ōsaka Furitsu Nakanoshima Toshokan) is a major library in the Nakanoshima section of Osaka, Osaka Prefecture, Japan.

It was established in 1904 and is today one of two libraries which are supported by the Osaka Prefectural government.

The Neo-baroque style is enhanced with four massive columns which stand at the building's front entrance. The building's stone walls harmonize with the other structures build on the island in the same period. The library's copper roof dome is a distinctive feature.

Initial construction was completed in 1904, and additional construction work in 1922 created an exterior appearance which remains to this day. The main building and both wings were designated as important cultural assets in 1974. It continues to function as a public library.

The library is located in the vicinity of Nakanoshima Park.
