In 1880, it was renamed to Aleksandrovo after the Bulgarian knyaz Alexander I of Battenberg. It was briefly named Vlaykovo in honour of Todor Vlaykov in 1936, but the name was changed back to honour Alexander as Knyaz Aleksandrovo in the same year. Finally, the modern name of Dimovo was established in 1951, after local partisan Zhivko Puev's nickname, Dimo.
