Gerrit Versteeg (Vlaardingen, 2 August 1872 – Arnhem, 1938) was a Dutch urban architect.
Versteeg studied in Delft for carpenter, and started his career at an architectural firm.
In this period many schools and commercial buildings were built, such as the tram depot, the slaughterhouse, the power plant and vegetable auction.
Versteeg then moved to Amsterdam, where in 1914 he started working together with the architect Jan Gratama.
They are also known by designing since 1916 many transformer houses for the electricity company PGEM (Provincial Geldersche Electriciteits Maatschappij).
