"Siftei Chakhamim" is a supercommentary on Rashi’s commentary on Chumash. Written by Shabbetai ben Joseph Bass (1641–1718) in Amsterdam, it is mostly a collection of other commentaries, in addition to the author's own insights, meant to give a basic understanding of Rashi. It is printed in almost all editions of "Mikraot Gedolot". An abridgement of this work, entitled "Ikar Siftei Chakhamim", appears in many editions of Chumash with Rashi.
