<P> Stanford Leonard Smith ( voiced by Seth MacFarlane ) is the title character on American Dad ! who has an exaggeratedly masculine voice and manner about him . Stan is Francine 's husband and Hayley and Steve 's father . Hayley may or may not be Stan 's biological daughter since Francine revealed to have cheated on Stan at a bachelorette party in the episode `` The Kidney Stays in the Picture '' , but Stan regards Hayley as his daughter . As the Smith family breadwinner , Stan is a CIA agent . Early on in the series , Stan was exaggeratedly patriotic and Conservative . His character , however , has progressed over the course of the series from the ultra right - wing it had been . All the same however , Stan has proven to be drastic and extreme in numerous other ways beyond politics . He is often shown rashly taking extreme measures in ways that are conspicuously destructive , disastrous , and life - threatening to others . Making his extreme - measure taking worse , Stan is utterly inconsiderate and insensitive , thus he does not stop to think of how others are negatively impacted , nor does he care . As examples of this : in the episode `` Dope & Faith '' when Stan found out one of his friends was an atheist , he tried getting him to pray by blowing up his home , spreading the bird flu at his restaurant , brainwashing his wife into thinking she was a lesbian , and taking his kids away ; in the episode `` I Ca n't Stan You , '' Stan evicted his entire neighborhood and his own family just for overhearing some of his neighbors gossiping about him behind his back ; in the episode `` Four Little Words , '' Stan framed his wife as a murderer all so as not to hear her say the words `` I told you so '' ; etc . Not a stranger to going to any and all lengths to achieve his desired ends -- even to the point of shamelessly harming others -- Stan is characterized as very dog - eat - dog . Aside from his thoughtlessly drastic and endangering behaviors , he has an endearing and sensitive side as well . It has been revealed that he very much desires fatherly love and attention but has always lacked this . Stan 's parents separated when he was very young ( later learned because of Stan himself in the episode `` Blood Crieth Unto Heaven '' ) ; thus he has a father ( Jack Smith ) who was not around much and mistreated him . </P>
