Johannes Hermanus Koekkoek, (Veere, 17 August 1778 – Amsterdam, 9 January 1851) was a Dutch painter and draughtsman.
Koekkoek was the head of an artistic family. His sons Barend Cornelis Koekkoek, Hermanus Koekkoek (1815–1882) and Marinus Adrianus Koekkoek (1807–1868) were all successful artists; the first two specialized in marine art, and Marinus was primarily a landscape painter. His grandson Johannes Hermanus Barend Koekkoek also became an artist.
Johannes Hermanus Koekkoek initially trained under Thomas Gaal, working in a wallpaper factory. He became primarily a marine art and genre art painter. He was active between 1793 and 1851, and worked in Middelburg, Durgerdam, Amsterdam (1833–1851), and Medemblik (1838) and Katwijk aan Zee.
