Holmberg is a Swedish surname formed from the words holm(e) meaning islet and berg meaning mountain. It is a relatively common name, at least in Sweden, which has to do with the fact that many Swedish place names contain the suffixes -holm, -holmen or -berg, -berga, -berget. Notable people with the surname include: Åke Holmberg (1907–1991), Swedish author and translator. Anne Holmberg (born 1938), American writer of historical romance novels. Arvid Holmberg (1886–1958), Swedish gymnast who competed in the 1908 Summer Olympics.
