Sankhenre Sewadjtu was the thirty-fourth pharaoh of the Thirteenth Dynasty of Egypt during the Second Intermediate Period.

[1] Sankhenre Sewadjtu is unknown from contemporary historical records, and is exclusively attested by the Turin canon.

He is listed as the successor of Ini in the Turin Canon, on column 7 line 5, and is given a reign of 3 years and 2 to 4 months in this document.

[1] Kim Ryholt proposes that Sankhenre Sewadjtu is attested on the Karnak king list under a different name owing to a scribal error.

Ryholt thus proposes that the two remaining names refer to Sankhenre Sewadjtu and Seankhenre Mentuhotepi.
