What is the name of Dexter Morgan's son?

What is the name of Dexter Morgan's son? Dexter Morgan's son is Harrison Morgan.

Harrison is the biological son of Dexter Morgan and Rita Morgan. He is born near the beginning of season 4, adding a new responsibility to Dexter's already unstable life as a forensic analyst, husband, and secret vigilante serial killer. Dexter's exhaustion as a new father contributes to mistakes while he tries to maintain his hidden activities.

Harrison's childhood is marked by major trauma. At the end of season 4, he is discovered sitting in Rita's blood after the Trinity Killer murders her, echoing the childhood trauma that shaped Dexter himself. In the original series, Harrison is played by several infant and child performers.

The character becomes central again in Dexter: New Blood, where a teenage Harrison tracks Dexter to Iron Lake. The revival explores whether Harrison has inherited his father's violent impulses and whether Dexter can protect him from repeating the same destructive pattern. Harrison should not be confused with Astor and Cody, Rita's children from a previous relationship, or with Harry Morgan, Dexter's adoptive father.
