Year 357 (CCCLVII) was a common year starting on Wednesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Constantius and Iulianus (or, less frequently, year 1110 Ab urbe condita). The denomination 357 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

.357 may refer to:

• .357 (film), a film by Scott Rawsthorne
• .357 Magnum, a firearm cartridge (revolver)
• .357 SIG, a firearm cartridge (pistol)

Cyprus adopted a closed telephone numbering plan on 1 December 2001. As a result, for land line phone numbers the digit 2 followed by the old area code was affixed to the subscriber number and for mobile phones 9 was affixed to the phone number. The plan is also used in Akrotiri and Dhekelia.
