To provide a yarn end suction device of a loom, which can suppress a fluid consumption amount and prevent occurrence of a cutting error when sucking a weft yarn via a suction mouth disposed near the outside of a weaving end and discharging an unnecessary yarn end portion cut by a cutter to the exterior. In a yarn end suction device (1) of a loom, a weft yarn (2a) carried by a beating motion is sucked and captured via a suction mouth (5) disposed near the outside of a weaving end, then the weft yarn (2a) is cut by a cutter (4) provided between the weaving end and the suction mouth (5), and thereafter, a weft yarn end portion (2b) is discharged to the exterior. The suction mouth (5) has a suction port (7) that is formed so as to have a polygonal cross-sectional shape at its end portion, and one corner (8a) thereof is disposed so as to be directed toward the weaving end side.
