Monoxenous development, or monoxeny, characterizes a parasite whose development is restricted to a single host species.
The etymology of the terms monoxeny / monoxenous derives from the two ancient Greek words  (), meaning "unique", and  (), meaning "foreign".
In a monoxenous life cycle, the parasitic species may be strictly host specific (using only a single host species, such as gregarines) or not (e.g. Eimeria, Coccidia).
