Loek Hollander (20 May 1938 – 16 February 2020) was a prominent Dutch karate practitioner.

After Sosai Masutatsu Oyama's death, new director Shokei Matsui appointed Hollander to be a regional representative for the European and African nations.

In 1999, Matsui honored Hollander with the rank of 8th dan,[2] making him one of the highest-ranking members of the IKO Kyokushinkaikan.

Hollander was the International Committee Member for Europe and Africa within the IKO led by Shokei Matsui, until August 13, 2010, when he resigned from the organization in protest.

In 2014 Loek Hollander was officially inducted into the CBME's National Hall of Fame for the Martial arts.
