Tuoba (Tabγač or Tabghach; also Taγbač or Taghbach; Chinese: 拓跋) is an extinct language spoken by the Tuoba people in northern China around the 5th century AD during the Northern Wei dynasty.
Alexander Vovin (2007) identifies the Tuoba language as a Mongolic language.
On the other hand, Juha Janhunen proposed that the Tuoba might have spoken an Oghur Turkic language. According to Peter Boodberg, the Tuoba language was essentially Turkic with Mongolic admixture. Chen Sanping noted that the Tuoba language "had both" Turkic and Mongolic elements.
Liu Xueyao stated that Tuoba may have had their own language, which should not be assumed to be identical with any other known languages.
Andrew Shimunek (2017) classifies Tuoba (Tabghach) as a "Serbi" (i.e., para-Mongolic) language. Shimunek's Serbi branch also consists of the Tuyuhun and Khitan languages.
