===Saturated cyclic hydrocarbons===
{{Main|Cycloalkane}}

Though technically distinct from the alkanes, this class of hydrocarbons is referred to by some as the "cyclic alkanes." As their description implies, they contain one or more rings.

Simple cycloalkanes have a prefix "cyclo-" to distinguish them from alkanes. Cycloalkanes are named as per their acyclic counterparts with respect to the number of carbon atoms in their backbones, e.g., [[cyclopentane]] (C<sub>5</sub>H<sub>10</sub>) is a cycloalkane with 5 carbon atoms just like [[pentane]] (C<sub>5</sub>H<sub>12</sub>), but they are joined up in a five-membered ring. In a similar manner, [[propane]] and [[cyclopropane]], [[butane]] and [[cyclobutane]], etc.

Substituted cycloalkanes are named similarly to substituted alkanes – the cycloalkane ring is stated, and the substituents are according to their position on the ring, with the numbering decided by the [[Cahn–Ingold–Prelog priority rules]].<ref name=reusch-nom/>
