Funiculus (Latin for "slender rope") is any cord-like structure in anatomy or biology, and may refer to:

* in the peripheral nervous system a bundle of axons that may be bundled into a nerve fascicle
* in the central nervous system one of the paired white matter regions of the spinal cord: the anterior funiculus, the lateral funiculus, and the posterior funiculus; and in the fourth ventricle the funiculus separans a strip of ependyma.
* the umbilical cord attaching a fetus to the placenta during pregnancy
* the spermatic cord formed by the vas deferens and surrounding tissue
* in insect antennae, the funicle is the segment connecting the club with the base
* in flowering plants, the funiculus is the stalk that attaches an ovule to the placenta
* in mycology, the funicular cord is a sticky trailing thread that attaches the peridioles (the "eggs") to the peridium (the "nest") in some species of bird's nest fungi
