Siegfried is a German language male given name, composed from the Germanic elements sig "victory" and frithu "protection, peace". The German name has the Old Norse cognate Sigfriðr, Sigfrøðr, which gives rise to Swedish Sigfrid (hypocorisms Sigge, Siffer), Danish/Norwegian Sigfred. In Norway, Sigfrid is given as a feminine name.
The name is medieval, and did survive in marginal use into the modern period, but after 1876 it enjoyed renewed popularity due to Wagner's Siegfried.
