Johannes Antonius van der Laan (4 May 1896 - 24 August 1966) was a Dutch architect.
After his father's death Jan had various partners in the architectural practice, which continued for many years to design significant buildings in the Netherlands.
The partners were: Jan Hermans and Theo van der Eerden, and later Jules Kirch and Henk Blansjaar, who continued the practice until 1984.
The practice was one of the largest in the Netherlands and specialised in work for Catholic clients in the style of the Delft School.
