Herman Ambrosius Jan Baanders

Herman Ambrosius Jan Baanders (Amsterdam, 13 February 1876 – Amsterdam, 27 May 1953), also known by his initials as H.A.J. Baanders, was a Dutch architect, designer and entrepreneur who was active in the Amsterdamse School style of architecture. He designed the Amsterdams Lyceum, among others.

Baanders' most significant contribution to the development of the Amsterdamse School style was a number of buildings outside Amsterdam during the early phase of the movement. His firm was also the starting point for the careers of a number of prominent Amsterdamse School architects, such as Michel de Klerk, Cornelis Blaauw, J. Zietsma, and Willem Maas.

In Amsterdam a street has been named for him, the H.A.J. Baanderskade in Zeeburg.
