"Allogona" is a land snail genus in the family Polygyridae. The shell is not distinguishable from "Triodopsis" but the male reproductive anatomy is unusual and characteristic for the genus. (The genus name, from Greek, means "different genitalia".) Pilsbry, Henry A. (1940). Land Mollusca of North America (North of Mexico). Acad. Nat. Sci. Philadelphia, Monograph 3, vol. 1(2): 875-892.]

The genus "Allogona" contains the following species and subspecies:
* "Allogona profunda"
* "Allogona profunda strontiana"
* "Allogona ptychophora"
* "Allogona ptychophora solida"
* "Allogona townsendiana"

The classic treatment of this group by Pilsbry divides the genus into two subgenera: "Allogona" "s.s." for "A. profunda" and its subspecies, and "Dysmedoma" for the other members of the taxon.
