Lymm Cross is in the village of Lymm, Cheshire, England. It is recorded in the National Heritage List for England as a designated Grade I listed building.
The cross dates from the early to the middle 17th century and it was restored in 1897. It is constructed of sandstone and stands on an artificially stepped natural outcrop of red sandstone. Its shaft stands in a square pavilion of red sandstone with square corner pillars. It has a stone roof with a pedimented gable to each face and ball finials. Above the cross is an extension which carries a stone ball and an ornate weather vane. On the east, south and west gables are bronze sundials of 1897 carrying the inscriptions "We are a Shadow", "Save Time" and "Think of the Last".
