The precipitate formation and behavior in nitrogen-containing high-entropy alloy of equiatomic CoCrFeMnNi were characterized. The presence of 0.95 at.% nitrogen led to the formation of Cr2N precipitate in the as-recrystallized N-CoCrFeMnNi, in which annealing temperature affected the fraction and size of the formed Cr2N particles. It was observed that the Cr2N exhibited a Kikuchi crystal orientation relation (OR) with the face-centered cubic (FCC) matrix, and the OR was noticed to be in the plane of {1 1 1}gamma//{0 0 0 1}Cr2N and direction of < 1 1 0 >gamma//< 1 (1) over bar 00 > Cr2N.
