Bukobaja is an extinct genus of mastodonsaurid temnospondyl from the middle Triassic of Russia. It contains a single species, Bukobaja enigmatica. Bukobaja mainly occurs in the Bukobay Svita as part of the Ladinian?-age "Mastodonsaurus fauna", a section of Russian Triassic biostratigraphy characterized by "Mastodonsaurus" torvus. It was also present in the underlying Donguz Svita ("Eryosuchus fauna").{{cite book|last1=Shishkin|first1=M.A.|title=The Age of Dinosaurs in Russia and Mongolia|last2=Ochev|first2=V.G.|last3=Lozovskii|first3=V.R.|last4=Novikov|first4=I.V.|publisher=Cambridge University Press|year=2000|isbn=9780521545822|editor=Benton, M.J.|location=Cambridge|pages=140–159|chapter=Tetrapod biostratigraphy of the Triassic of Eastern Europe|editor2=Shishkin, M.A.|editor3=Unwin, D.M.|editor4=Kurochkin, E.N.}}{{Cite journal|last1=Tverdokhlebov|first1=Valentin P.|last2=Tverdokhlebova|first2=Galina I.|last3=Surkov|first3=Mikhail V.|last4=Benton|first4=Michael J.|date=2003-01-01|title=Tetrapod localities from the Triassic of the SE of European Russia|url=http://www.sciencedirect.com/science/article/pii/S0012825202000764|journal=Earth-Science Reviews|language=en|volume=60|issue=1|pages=1–66|doi=10.1016/S0012-8252(02)00076-4|bibcode=2003ESRv...60....1T |issn=0012-8252}} Bukobaja appears to be a valid genus similar to, yet distinct from, Mastodonsaurus. Despite appearing to possess several unique features, Bukobaja is still known from very few remains. This has led to difficulties in determining its relations more precisely than "Mastodonsauridae incertae sedis".{{Cite journal|last=Damiani|first=Ross J.|date=2001-12-01|title=A systematic revision and phylogenetic analysis of Triassic mastodonsauroids (Temnospondyli: Stereospondyli)|journal=Zoological Journal of the Linnean Society|language=en|volume=133|issue=4|pages=379–482|doi=10.1111/j.1096-3642.2001.tb00635.x|issn=0024-4082|doi-access=free}} It has also been compared to trematosaurids.{{Cite journal|last=Schoch|first=Rainer R.|date=2006-03-30|title=A complete trematosaurid amphibian from the Middle Triassic of Germany|url=https://www.tandfonline.com/doi/abs/10.1671/0272-4634%282006%2926%5B29%3AACTAFT%5D2.0.CO%3B2|journal=Journal of Vertebrate Paleontology|volume=26|issue=1|pages=29–43|doi=10.1671/0272-4634(2006)26[29:ACTAFT]2.0.CO;2|s2cid=85829091 |issn=0272-4634}}
