Jan Kříženecký (20 March 1868 – 9 February 1921) was a Czech cinema pioneer, film director, cinematographer and photographer.

Since 1903 he worked as professional photographer documenting the soon to be demolished houses in the streets of Prague for Municipal Building Authority.

He started showing Lumières' as well as his own short documentary films at pavilion in Prague's Výstaviště during Architecture and Engineering Exhibition in June 1898.

He died forgotten in 1921 and none of the four Czech film magazines at that time reported his death.

The character Kolenatý in Jiří Menzel's Those Wonderful Movie Cranks (1978) is based on Kříženecký.
