Ogdoconta moreno is a moth in the family Noctuidae first described by William Barnes in 1907.

It is only known from southern Arizona in the US, although its distribution likely extends into Mexico.

The antemedial line is angled with the outward apex occurring just below the orbicular spot.

The postmedial line is an almost straight, light line, followed by a light tan or gray region of the subterminal area, which gradually becomes darker in the subterminal area.

Adults have been recorded on wing in July, August and September.
