Are there any crossover missions between gta online and story mode?

Grand Theft Auto V offers a distinct single‑player narrative and a separate multiplayer experience in GTA Online. While both games share the same world and many of the same locations, Rockstar has not released any missions that specifically merge the story mode’s linear progression with the cooperative or competitive structure of Online. Players can, however, participate in certain story‑mode missions within Online’s story‑mode‑style missions, and some Online events feature story‑mode characters, but these are treated as separate content streams rather than true crossovers. Consequently, there is no official gameplay content that requires completion of story mode missions to unlock Online missions or vice versa.
