Johannes Hermanus Koekkoek was a Dutch painter and draughtsman.

Johannes Hermanus 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.
