Tronchi is the plural form of the Italian noun tronco. The term denotes a central, supporting axis or main stem in several contexts, most commonly referring to the trunk of a plant or tree, but also used for the body’s main torso and, more generally, as a metaphor for the central part of something.

In botany and forestry, tronco refers to the trunk of a tree or other woody plant, the principal vertical axis that bears the crown. It can also denote sections obtained from a felled tree, such as logs or the remaining stump. In forestry and timber terminology, tronchi are described by characteristics like diameter, height, volume, and timber quality.

In anatomy, tronco means the trunk or torso of a human or animal, comprising the thorax, abdomen, and pelvis, and excluding the head and limbs. In medical or anatomical writing, the term highlights the central body region and its relation to the limbs.
