Was don knott's wife on the Andy griffith show?

No, Don Knotts' wife was not a regular character on "The Andy Griffith Show." Knotts played the role of Barney Fife, but his character's personal life, including his marital status, was not a focal point of the show. While Knotts' character had various romantic interests throughout the series, his actual wife, Kathryn, did not appear on the show.
