Millwall suffered the ill fortune of becoming a founding member of Division Four in 1958. While initially suffering from this reorganisation, the de-regionalisation of Third Division North and Third Division South opened up the way for promotion via the runner up spots. Millwall won the Division Four Title in 1962 with the help of 23 Goals from Peter Burridge and 22 from Dave Jones. They were relegated again in the 1963–64 season, but were to bounce back by winning back-to-back promotions as runner up. This is the last time Millwall played in the fourth tier.
