The Grey Tortrix (Cnephasia stephensiana) is a moth of the Tortricidae family. It is found in the Palearctic ecozone, and has also been recorded from Canada.

The wingspan is 18–23 mm. Adults are on wing from May to August.

Eggs are laid in July and August and hatch after about three weeks. The young caterpillars make a cocoon in which they overwinter. They start feeding in spring. In the beginning they mine. Later they live in folded leaves. The caterpillars pupate from April to July.

The larvae are polyphagus and have been recorded from over 120 plant species. It is sometimes considered a plague on various agricultural crops.
