Observations were made of the 2.121-micron 1-0 S(1) emission line of H2 from the direction of the Orion Nebula, using a Fabry-Perot spectrometer which had a velocity resolution of 11 km/s. The line was found to have a centroid velocity of plus 9.3 plus or minus 1.5 km/s with respect to the local standard of rest and a FWHM of 12.9 plus or minus 4.1 km/s. There are no obvious indications of line splitting. These measurements put significant constraints on various models for the origin of the H2 emission.
