Pinguicula orchidioides is a perennial rosette-forming insectivorous herb native to Mexico and Guatemala. A species of butterwort, it forms summer rosettes of flat, succulent leaves up to 5 centimeters (2 in) long, which are covered in mucilaginous (sticky) glands that attract, trap, and digest arthropod prey. Nutrients derived from the prey are used to supplement the nutrient-poor substrate that the plant grows in. Uniquely among Pinguicula species from the Americas, p. orchidioides produces gemma-like basal buds which elongate into stolons and serve as a means of asexual reproduction. In the winter the plant forms a non-carnivorous rosette of small, fleshy leaves that conserves energy while food and moisture supplies are low. Single purple flowers appear between July and September on upright stalks up to 22 centimeters long.

The species was first described in 1844 by Alphonse Pyrame de Candolle, but following an unfortunate misidentification by his contemporary William Jackson Hooker, was relegated to the ranks of botanical synonymy and generally forgotten until it was rediscovered through the works of botanists in the 1990s.

The generic name Pinguicula is derived from the Latin pinguis (meaning "fat") due to the buttery texture of the surface of the carnivorous leaves. The specific epithet orchidioides refers to dainty, orchid-like flowers.
