结肠带（taeniae coli，也作teniae coli或tenia coli）是结肠外壁的三条纵向平滑肌带，对应消化道其他部位的肌外层（英语：muscularis externa），为结肠的特化组织，在乙状结肠以前的结肠（升结肠、横结肠、降结肠）均存在。结肠带肉眼可见，位于结肠的最外层（浆膜（英语：Serous membrane）或纤维膜（英语：Fibrosa））之下，可细分为mesocolic、free、omental三条。结肠带的收缩会造成结肠袋（英语：Haustra）的产生。结肠带在阑尾开始处一分为三；在乙状结肠－直肠连接处（英语：rectosigmoid junction），三条结肠带则分散开来并合而为一，成为纵向肌肉层。结肠带受副交感神经调控，其神经由脊髓的荐椎部分出。^[1]

Lambert, H. Wayne; Wineski, Lawrence E. Anatomy & Embryology. Lippincott Williams & Wilkins. 2011: 65. Destruction of the sacral spinal cord will eliminate parasympathetic outflow to the hindgut, pelvic organs, and perineum as well as somatic innervation to much of the pelvis and lower limbs. Because it stimulates gut motility and tone, loss of parasympathetic input will result in relaxation and inactivity of the teniæ coli in the descending colon.
