Luciano "Luke" Eduardo Snyder (also Grimaldi) is a fictional character from the American daytime drama As the World Turns.

When Luke was born, his mother Lily Walsh did not know whether his father was her then-spouse Damian Grimaldi or her lover Holden Snyder.

When Luke was a teenager, he confessed to the murder of Julia Larrabee, who he blamed for breaking up his parents' marriage, to protect his mother, who he thought was guilty of the crime.

When the true killer was found to be somebody else, his life did not return to normalcy; as his mother began dating another man, Keith Morrissey, Luke became an alcoholic.

While a pregnant Lily can't accept her eldest son's sexual orientation, the rest of his family supports him.

When Lily realizes the nature of the camp, she tries to reassure Luke that she will accept him, but thinking her the sole responsible party he lashes out angrily at her for her betrayal, inadvertently knocking her down the stairs.

He severs ties with his birth father, changing his name, but yields his share in the Grimaldi family fortune to Damian before he goes.

Lily, who gave birth while in her coma, finally emerges to also reconcile with Luke and, to everyone's surprise, Jade turns out not to be a fraud after all.

Unfortunately, Colonel Mayer learns the secret when he catches them in their second kiss and rejects Noah before devising a plan to murder Luke.

His efforts leave Luke paralyzed for a time, although physical therapy, and Noahs help, eventually put him back on his feet.

Their relationship is challenged when Noah, to save a young Iraqi woman with connections to his father from deportation, decides to marry her.

He winds up cheating to overcome a dirty campaign by Kevin and is expelled when Noah comes clean to the dean about what Luke did.

Ostracized, Brian comes very close to suicide before Luke and Noah can intervene, but after their intervention, he makes peace with Lucinda and his own homosexuality before leaving town.

Their involvement starts out a bit rocky when Noah gets his sight back, and refuses to reunite with Luke after seeing him and Dr. Oliver kissing.

Feeling loyalty toward Noah, and guilt for falling for his doctor, Luke has a hard time figuring out who he wants to be with, in most cases, rebuking the Dr.s advances.

Noah tells Luke to stay in Oakdale, grieve, and heal, and that he will be waiting for him, leaving the door open to reconciliation.
