Kozlov was born in the village of Loshchinino (Russian: ), Ryazan Province. Between 1953 and 1957, Kozlov was the first secretary of the Leningrad Oblast CPSU Committee. He was elected a candidate member of the Presidium (as the Politburo of the Central Committee of the Communist Party of the Soviet Union was then called) on 14 February 1957 and served as a full member from 29 June 1957 until he was relieved of his duties on 16 November 1964, following the ousting of his mentor, Nikita Khrushchev, a month earlier.
For many years, he was considered Khrushchev's likely successor  but even before his mentor's removal from office, Kozlov's position had been undermined by the effects of his alcoholism; in the spring of 1963 he was replaced by Leonid Brezhnev as Secretary of the Communist Party Central Committee. At the time of his removal, Kozlov had already suffered a stroke, and he died shortly after his removal from office.
He was buried in the Kremlin Wall Necropolis.
