Brodmann area 19, or BA19, is part of the occipital lobe cortex in the human brain. Along with area 18, it comprises the extrastriate (or peristriate) cortex. In normally-sighted humans, extrastriate cortex is a visual association area, with feature-extracting, shape recognition, attentional, and multimodal integrating functions.

Area 19 in humans is likely to be homologous to area V3 in the primate. It has reciprocal connections with areas 17 and 18, as well as posterior parietal association areas.

Rostrally it is bounded by the angular area 39 (H) and the occipitotemporal area 37 (H) (Brodmann-1909).
Single-cell electrophysiological recordings from area 19 in the cat suggest sensitivity to motion-delineated forms; recordings from primates have yielded varying results, indicating that this area may be a heterogeneous collection of visual areas, with multiple incomplete representations of the visual scene.
Area 19 has been noted to receive inputs from the lateral geniculate nucleus via the pulvinar, and may contribute to the phenomenon of blindsight.
