The Alexander Library Building is located in the Cultural Centre of Perth, Western Australia.

It was named after Western Australian historian and former member of the Library Board, Fred Alexander.

The building falls under the responsibility of the Western Australian government Department of Culture and Arts.

The street had a unique streetscape, one of the most mixed in this area of the Perth central business district – which was all removed in the construction of the new library building.

The Theosophical Bookshop and library was long established at the corner of Museum and James Streets.
