Andrianavoay (meaning "noble crocodile" in Malagasy) is an extinct genus of teleosauroid from the Bathonian (in the Middle Jurassic), probably from the Isalo III Formation of Madagascar.

[1] The type species, A. baroni, was originally named "Steneosaurus" baroni by ET Newton in 1893 on the basis of a partial skull listed as "NHMUK PV R 1999",[2] and an associated osteoderm from Andranosamonta, Madagascar.

[2] In her unpublished 2019 thesis, Michela Johnson coined the nomen (ex dissertatione) Andrianavoay for S.

baroni.

[3] The genus name was published in 2020.
