The Woolly Worm is an artificial fly commonly categorized as a wet fly or nymph and is fished under the water surface. It is a popular pattern for freshwater game fish and was a very popular fly in the 1950s–1970s in the west. Charles Brooks in Nymph Fishing for Larger Trout recommends the Woolly Worm as a general purpose nymph pattern in most western trout waters in any fly box.

Today, Woolly Worms are tied in a variety of styles and colors to imitate a large aquatic nymphs such as stoneflies, dragonflies, damselflies or hellgrammites.

The original Woolly Worm pattern is said to have originated in the Ozarks as a bass fly. Its real popularity however came when Don Martinez, a West Yellowstone, Montana fly tier commercialized the pattern in the 1950s.
