The club was founded in 1957 and reached the second tier after winning Liga Bet South B Division in the 1970–71 season. After several lower-table finishes, the club was relegated to Liga Alef at the end of the 1978–79 season, in which they finished bottom. They returned to the second division at the end of the 1989–90 season, in which they won the southern division of Liga Alef, beating local rivals Maccabi Ironi Ashdod to the title by a single point.

However, the club merged with Maccabi Ironi Ashdod, to form F.C. Ashdod. In 2001 a new club, Hapoel Namal Ashdod was established, playing in Liga Gimel. Although the club was initially successful, winning its division and gaining promotion to Liga Bet, at the end of the 2003–04 season, in which it finished fourth, it was disbanded.
Re-established club
In March 2015, fans of Hapoel Ashdod gathered and re-established the club, with the purpose of joining Liga Gimel in the 2015–16 season. Later on that month, F.C. Ashdod's chairman, Jacky Ben-Zaken, decided to rename F.C. Ashdod to Hapoel Ashdod and to play in red shirts, following a dispute with fans of the previous club, Maccabi Ironi Ashdod. Despite warnings from the Israel Football Association, which informed the club that such changes during season are illegal, F.C. Ashdod did show up for their Bottom playoff match against Hapoel Ra'anana in red shirts, with the caption "F.C. Hapoel Ashdod", and was eventually disciplined. However, Hapoel Ashdod fans have decided that the club will be registered in Liga Gimel, rather than joining forces with Ben-Zaken's F.C. Ashdod. At the same time, another group of Hapoel Ashdod fans, headed by lawyer Ya'akov Shitrit, formed a second club, due to play in 2015–16 Liga Gimel. As Shitrit's group was affiliated with the Hapoel organization, this club was registered in the IFA under the name Hapoel Bnei Ashdod, while the fans' club was forced to drop the name Hapoel from their club and registered under the name of Agudat Sport Ashdod,.
