The Yenoma Ledger is a worked plaque of mammoth ivory reportedly recovered from yedoma permafrost in the lower Indigirka region of northeast Siberia.

A preliminary technical report describes controlled cold-chain recovery and non-destructive documentation, but does not advance a cultural attribution or secure the age of the carving itself.<ref>J.
