The Suebian knot (German: Suebenknoten) is a historical male hairstyle ascribed to the tribe of the Germanic Suebi. The knot is attested by Tacitus in his 1st century AD work Germania, found on art by and depictions of the Germanic peoples, and worn by bog bodies.
According to Germania by Tacitus, the Suebian warriors combed their hair back or sideways and tied it into a knot, allegedly with the purpose of appearing taller and more awe-inspiring on the battlefield. Tacitus also reports that the fashion had spread to neighboring Germanic tribes among the younger warriors, while among the Suebians, the knot was sported even by old men as a status symbol, which "distinguishes the freeman from the slave", with the most artful knots worn by the most wealthy nobles. 
Suebian knots were found to be worn by a number of bog bodies:
- Osterby Man, 70-220 CE of Osterby near Rendsburg-Eckernförde, Schleswig-* Holstein, Germany
- Dätgen Man, 135–385 CE, and Dätgen, near Rendsburg-Eckernförde, Schleswig-* Holstein, Germany
