The Lakeside Hammers were a speedway team who most recently raced in the SGB Championship in 2018. They were founded (as the Arena-Essex Hammers) by promoter Wally Mawdsley and stock car promoter Chick Woodroffe. The team were nicknamed the Hammers after the West Ham Hammers, a speedway team that closed twelve years earlier. The team's home track, the Arena Essex Raceway, closed shortly before the end of the 2018 season and the team did not compete in a league in 2019.
