Ulrich Gabler (1 October 1913 – 24 February 1994) was a German shipbuilding engineer, who specialized in the design and development of diesel-powered submarines.

During World War II he served as chief engineer in the U-boat force on U-121 and U-564, then under the command of Reinhard Suhren. Suhren had recommended Gabler for the Knight's Cross of the Iron Cross, a request that was turned down and Gabler received the German Cross in Gold on 15 October 1942. Following his war patrols on U-564 he worked on the design and development of the U-boat classes XXII, XVII A and XXVI.^{[citation needed]}

After the war he founded the Ingenieurkontor Lübeck (IKL) which among others designed the type 201, 202, 205 and 209 submarines.^{[citation needed]}

In 1963 he was appointed honorary professor at the University of Hamburg for shipbuilding.^{[citation needed]}
