TurnTide Inc. was an anti-spam technology company founded in 2004 and based in Conshohocken, Pennsylvania. The firm was created as a spin-off corporation from privacy and anti-spam technology firm ePrivacy Group to bring to market the world's first anti-spam router. The technology, linking anti-spam detection algorithms with network-level flow controls, was originally marketed by ePrivacy Group under the name "SpamSquelcher".

TurnTide was acquired by Symantec six months after its creation for US$28 million. In 2006, the TurnTide technology was described as "magic" by John Katsaros at the Internet Research Group.{{cite web |url=http://www.internetacceleration.com/newsletters/email-9-29-06.htm |title=Archived copy |website=www.internetacceleration.com |access-date=12 January 2022 |archive-url=https://web.archive.org/web/20100328113940/http://www.internetacceleration.com/newsletters/email-9-29-06.htm |archive-date=28 March 2010 |url-status=dead}}
