Pedicularis semibarbata, known by the common name pinewoods lousewort, is a species of flowering plant in the family Orobanchaceae.

The leaves are up to 20 centimeters long, lance-shaped shape and divided into many toothed or lobed segments.

Each hairy red- or purple-tinged yellow flower is club-shaped and may exceed 2 centimeters in length.

This species taps nutrients from conifers and the lupine Lupinus fulcratus.

[1] Some authors recognize the Pedicularis semibarbata subtaxon charlestonensis, which is endemic to Nevada.
