Abstract: Provided are a condensed cyclic compound and an organic light-emitting device including the same. The organic light-emitting device may include a first electrode, a second electrode, and an organic layer disposed between the first electrode and the second electrode. The organic layer may include the condensed cyclic compound represented by Formula 1: In Formula 1, rings A1, A2, and A3 may each be independently a C5-C60 carbocyclic group or a C2-C30 heterocyclic group, and n1 to n3 may each be independently 0 or 1, provided that the sum of n1, n2, and n3 is 1. In addition, the descriptions of X1, L1 to L9, a1 to a9, Ar1 to Ar6, b1 to b6, R1 to R3, and c1 to c3 are as defined in the present specification.
