PROBLEM TO BE SOLVED: To obtain a dyed cellulosic fiber yarn on which fibrils are scarcely generated and which has excellent clarity, dyed color fastness and appearance grade and are useful for fabrics, or the like, by dyeing a cellulose multi-filament yarn having an X-ray crystal orientation degree in a prescribed range. SOLUTION: This dyed cellulosic yarn is obtained by dyeing a cellulose multi-filament yarn having an X-ray crystal orientation degree of 70-85% and preferably having a kinetic viscoelasticity peak top temperature Tmax of 252-280 deg.C, a tanδof 0.062-0.090 at the time and a yarn surface occupation rate of >=30% with a reactive dye, or the like.
