The greyish piculet (Picumnus granadensis) is a species of bird in subfamily Picumninae of the woodpecker family Picidae.

Adult males of the nominate subspecies have a black crown and nape with small yellow tips on the feathers of the front and top and white spots on the rest.

Their iris is brown, the beak black, the bare skin around the eye gray-blue, and the legs gray with a green or blue tinge.

Subspecies P. g. antioquensis has grayer upperparts and more obvious gray streaking on their belly and flanks than the nominate.

It inhabits semi-open landscapes like the edges of dry to somewhat humid primary and secondary forest, scrublands, and open woodlands.

It has a small range and its population size is unknown and believed to be decreasing, but none of the criteria pass the threshold to rate it Near Threatened.
