Terissa Dyson is a fictional housewife and a minor character featured in the Terminator multimedia franchise. She first appeared in the 1991 film Terminator 2: Judgment Day where she was originally played by actress S. Epatha Merkerson. The character also appeared in two episodes of Terminator: The Sarah Connor Chronicles, only this time she was played by Charlayne Woodard. She appeared in the series' pilot episode and "The Turk".
Terissa Dyson lived in Los Angeles, California in the 1990s. She was the wife (later widow) of scientist Miles Dyson and the mother of Danny Dyson. In 1995, Terissa Dyson was present in the family residence when Sarah Connor attempted to assassinate Miles, whom she believed was destined to invent a super-computer that would ultimately lead to the destruction of the world. Although Miles survived Sarah's attempt to kill him, he later gave his own life to change the course of future history. 
In 1999, Sarah Connor revisited the Dyson home. Terissa still believed that Sarah was responsible for Miles' death and ordered her to leave her home. Sarah explained that Judgment Day was still coming and that Miles' sacrifice, now seemingly in vain, only changed the time table. She needed information from Terissa about anyone from Miles' past who might have had access to his notes.
