Germanic tribe attested only for their role in the Marcomannic Wars (reign of Marcus Aurelius, 161-180): after an initial Roman-allied Vandal (Hasdingi/'Astingi') incursion was pushed back, the Lacringi — fearing Roman retaliation — turned on their allies and routed them in a surprise attack.
No further activity is recorded after the Marcomannic Wars episode; likely absorbed into neighboring Dacian-frontier groups.
