Polycyclic may refer to:
*
Polycyclic compound
In the field of organic chemistry, a polycyclic compound is an organic compound featuring several closed ring (chemistry), rings of atoms, primarily carbon. These ring substructures include cycloalkanes, aromaticity, aromatics, and other ring ...
, a cyclic compound with more than one hydrocarbon loop or ring structures, including:
**
Polycyclic musks
Synthetic musks are a class of synthetic aroma compounds to emulate the scent of deer musk and other animal musks (castoreum and Civet (perfumery), civet). Synthetic musks have a clean, smooth and sweet scent lacking the fecal notes of animal musk ...
**
Polycyclic aromatic hydrocarbon
A Polycyclic aromatic hydrocarbon (PAH) is any member of a class of organic compounds that is composed of multiple fused aromatic rings. Most are produced by the incomplete combustion of organic matter— by engine exhaust fumes, tobacco, incine ...
***
Chlorinated polycyclic aromatic hydrocarbon Chlorinated polycyclic aromatic hydrocarbons (Cl-PAHs) are a group of compounds comprising polycyclic aromatic hydrocarbons with two or more aromatic rings and one or more chlorine atoms attached to the ring system. Cl-PAHs can be divided into two g ...
***
Contorted polycyclic aromatic hydrocarbon
In organic chemistry, contorted aromatics, or more precisely contorted polycyclic aromatic hydrocarbons, are polycyclic aromatic hydrocarbons (PAHs) in which the fused aromatic molecules deviate from the usual Molecular geometry, planarity.

Polycyclic group
In mathematics, a polycyclic group is a solvable group that satisfies the maximal condition on subgroups (that is, every subgroup is finitely generated). Polycyclic groups are finitely presented, which makes them interesting from a computational ...
, in mathematics, a solvable group that satisfies the maximal condition on subgroups
*
Polycyclic spawning
Reproduction (or procreation or breeding) is the biological process by which new individual organisms – "offspring" – are produced from their "parent" or parents. There are two forms of reproduction: asexual and sexual.
In asexual reprodu ...
, when an animal reproduces multiple times during its lifespan
