Tick-borne lymphadenopathy is infectious disease, an uncommon tick-borne rickettsiosis caused by Rickettsia slovaca. It is transmitted exclusively by the Dermacentor marginatus tick. It is endemic to parts of east and south Europe.{{Cite web |title=lymphadénopathie à tiques - Dictionnaire médical de l'Académie de Médecine |url=https://www.academie-medecine.fr/le-dictionnaire/index.php?q=lymphad%C3%A9nopathie%20%C3%A0%20tiques |access-date=2024-02-06 |website=www.academie-medecine.fr}}

Infection is associated with formation of an eschar at the site of the tick bite, constitutional symptoms (fever and pains), and lymphadenopathy chiefly affecting the neck. A maculopapular rash may sometimes also arise.
