The smoot /ˈsmuːt/ is a nonstandard, humorous unit of length created as part of an MIT fraternity pledge to Lambda Chi Alpha by Oliver R. Smoot, who in October 1958 lay down repeatedly on the Harvard Bridge between Boston and Cambridge, Massachusetts, so that his fraternity brothers could use his height to measure the length of the bridge.

One smoot is equal to Oliver Smoot's height at the time of the prank, 5 feet 7 inches (1.70 m). The bridge's length was measured to be 364.4 smoots (2,035 ft; 620.1 m) "± 1 εar" with the "±" showing measurement uncertainty and spelled with an epsilon to further indicate possible error in the measurement. Over the years the "±" portion and "ε" spelling have gone astray in many citations, including some markings at the site itself, but the "±" is recorded on a 50th-anniversary plaque at the bridge's end.
