Charles Hernan Carreon (born April 7, 1956) is an American trial attorney best known for his involvement in a legal dispute between The Oatmeal webcomic and content aggregator FunnyJunk.

In October 2005, Carreon was suspended by the Oregon State Bar for 60 days for the unlawful practice of law and failing to deposit or maintain client funds in trust.

[15][16] In June 2012, Carreon represented FunnyJunk.com in sending a demand letter alleging defamation and requesting damages from Matthew Inman of The Oatmeal in a long-standing copyright infringement dispute.

[19][20] On June 15, Carreon filed a pro se lawsuit Carreon v. Inman et al in United States District Court for the Northern District of California in Oakland against IndieGoGo, Inc., the American Cancer Society, and the National Wildlife Federation, for alleged improprieties related to an Oatmeal charity fundraiser created in response to the FunnyJunk demand.

[24] On June 21, the Electronic Frontier Foundation announced they were joining with the lead lawyer representing Inman, stating, "This lawsuit is a blatant attempt to abuse the legal process to punish a critic.
