After leaving office in 1982, Governor Byrne became a senior partner at Carella, Byrne, Bain, Gilfillan, Cecchi, Stewart & Olstein in Roseland, New Jersey (now Carella, Byrne, Cecchi, Olstein, Brody and Agnello, P.C.).
 Additionally, Byrne and his successor as governor, Thomas Kean, co-wrote a weekly column in The Star-Ledger, containing their "dialogue" on state and national public affairs and politics.
He has also taught courses at Princeton University and Rutgers University.

In 2014, Donald Linky, Byrne's former chief counsel, published a biography of the former governor called New Jersey Governor Brendan Byrne: The Man Who Couldn't Be Bought.

Despite not supporting all of his policies, Byrne said that Governor Chris Christie should run for president in 2016, calling Christie "the best candidate that the Republicans have" and complimented his "charm".
