The Toyomiyazaki Bunkō (豊宮崎文庫) was a library and academy in the Edo period located in the Okamoto neighborhood of the city of Ise, Mie, Japan. It was an important resource for kokugaku scholars in the Bakumatsu period. Along with the Kanazawa Bunko and Ashikaga Bunko, it was one of the largest and most important collections in pre-modern Japan. The building once housing the collection was designated a National Historic Site of Japan in 1923.
