Francis Joseph McKenna PC OC ONB KC (born January 19, 1948) is a Canadian businessman and former politician and diplomat.

He garnered a place in contemporary Acadian folklore as the defence lawyer in the high-profile widely publicized murder case of famous New Brunswick boxing champion, Yvon Durelle.
