Elachista tengstromi is a moth of the Elachistidae family. It is found from Fennoscandia to Switzerland and Austria, and from Great Britain to Poland.
It was formerly considered to be a form of Elachista regificella.
The wingspan is 7-9,3 mm.
The larvae feed on Luzula pilosa. They form a strongly contracted upper-surface tentiform mine, generally in the lower third of the leaf, beginning at the leaf base. Mostly, a second or third mine is made which starts at the leaf tip. Pupation takes place outside of the mine.
