Tyska Stallplan (Swedish: "German Stable Square" or literally "Plane") is a street in Gamla stan, the old town in central Stockholm, Sweden.
Stretching south from Svartmangatan to Prästgatan, it is connected to Baggensgatan and Mårten Trotzigs Gränd, while forming a (somewhat) parallel street to Österlånggatan and Tyska Brinken.
While named a square, it undoubtedly remains a matter of taste and definition whether this elongated open space should be regarded as a street.
In the southern end of Tyska Stallplan several such traces have been discovered, and in Prästgatan, south of the street, lines of cobble stones have been used to indicate the former extent of the monastery.
On the square is a granite sculpture by Ivar Johnsson from 1956 depicting a young man mounting a horse.
