We prove that the set of long cycles has the edge-Erdős-Pósa property: for every fixed integerℓ≥ 3 and everyk∈ ℕ, every graphGeither containskedge-disjoint cycles of length at leastℓ(long cycles) or an edge setXof sizeO(k2logk+kℓ) such thatG—Xdoes not contain any long cycle. This answers a question of Birmelé, Bondy, and Reed (Combinatorica27(2007), 135-145).
