Detective Joe West is the father of Iris West.

When the Flash went back in time to save his mother from the Reverse Flash, he caused the events after that point to be rewritten into a new timeline called "Flashpoint."

In this timeline, Barry's mother was never killed, so his father never went to jail for her murder, so Barry was never adopted by the Wests. Wally, instead of being born without Joe's knowledge, was always a part of the family.

After regretting his part in rewriting history, the Flash has the Reverse Flash go back in time and kill his mother again in an attempt to put the timeline back to the way it was before, in effect erasing the Flashpoint timeline and this version of Joe West with it.[1]
