Irving Leonard Finkel (born 1951) is an English philologist and Assyriologist. He is the Assistant Keeper of Ancient Mesopotamian script, languages and cultures in the Department of the Middle East in the British Museum, where he specialises in cuneiform inscriptions on tablets of clay from ancient Mesopotamia.

Finkel was born in 1951 to a dentist father and teacher mother, one of five children, and grew up at Palmers Green, North London. He was raised as an Orthodox Jew but became an atheist as a teenager. He earned a PhD in Assyriology from the University of Birmingham under the supervision of Wilfred G. Lambert with a dissertation on Babylonian exorcistic spells against demons

Finkel spent three years as a Research Fellow at the University of Chicago Oriental Institute. In 1976 he returned to the UK, and was appointed Assistant Keeper in the Department of Western Asiatic Antiquities at the British Museum, where he was (and remains) responsible for curating, reading and translating the museum's collection of around 130,000 cuneiform tablets.

In 2014, Finkel's study of a cuneiform tablet that contained a flood narrative[8] similar to that of the story of Noah's Ark, described in his book The Ark Before Noah, was widely reported in the news media.The ark described in the tablet was circular, essentially a very large coracle or kuphar and made of rope on a wooden frame. The tablet included sufficient details of its dimensions and construction to enable a copy of the ark to be made at about 1/3 scale, as documented in a 2014 TV documentary Secrets of Noah's Ark that aired as an episode of PBS's NOVA series.[11] The reconstructed ark was floated with partial success given that the bitumen used as sealant for the vessel walls immediately succumbed to leaks and a gasoline powered pump had to continuously be used to pump out water.
