Bukobaja is an extinct genus of mastodonsaurid temnospondyl from the middle Triassic of Russia.

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.

[1][2] 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".
