The suffix -ane in organic chemistry forms the names of organic compounds where the -C-C- group has been attributed the highest priority according to the rules of organic nomenclature. Such organic compounds are called alkanes. They are saturated hydrocarbons.

The names of the saturated hydrides of non-metals end with the suffix -ane: the hydrides of silicon are called silanes SiH₄; the hydrides of boron are boranes B₂H₆.

The final "-e" is dropped before a suffix that starts with a vowel, e.g. "propanol".

Alternatively, -ane may be used for a mononuclear hydride of an element. For instance, methane for CH₄ and oxidane for H₂O (water). For the etymology, see Alkane.
