A Jupiter Column (German: Jupitergigantensäule or Jupitersäule) is an archaeological monument belonging to a type widespread in Roman Germania. Such pillars express the religious beliefs of their time. They were erected in the 2nd and 3rd centuries AD, mostly near Roman settlements or villas in the Germanic provinces. Some examples also occur in Gaul and Britain.

The base of the monuments was normally formed by a Viergötterstein (four gods stone), in itself a common monument type, usually depicting Juno, Minerva, Mercury and Hercules. This would support a Wochengötterstein (a carving depicting the personifications of the seven days of the week), which, in turn, supported a column or pillar, normally decorated with a scale pattern. The column was crowned with a statue of Jupiter, usually on horseback, trampling a Giant (usually depicted as a snake). In some cases (e.g. at Walheim), the column capital is decorated with four heads, usually interpreted as depictions of the four times of day (morning, midday, evening, night). The total height of a Jupiter Column is normally around 4 m, but some examples are taller, e.g. a famous example at Mainz with a height of more than 9 m.

The columns in Upper Germany normally depict Jupiter defeating a Giant, as described above, and are thus known as Jupitergigantensäulen ("Jupiter-Giant-Columns"). In Lower Germany, Jupiter is normally depicted enthroned without the Giant; those monuments are commonly described simply as Jupitersäulen ("Jupiter Columns").

The pillars were often placed within a walled enclosure and accompanied by an altar.

No such monument has survived intact. They are known from excavated finds or from secondary use as spolia, e.g. in Christian churches. Recently, reconstructions of some Jupiter Columns have been erected at or near where they were found, e.g. in Ladenburg, Obernburg, Benningen am Neckar, Sinsheim, Stuttgart, Mainz and near the Saalburg.
