Tiwagorn Withiton

Tiwagorn Withiton (; ; born 31 October 1975) is a Thai political and human rights activist, farmer and engineer. He is one of the first political activists in Thailand that openly challenge the country's taboo, harsh punishment under the lèse-majesté law, by publishing a photo of him wearing a printed 'I lost faith in the Monarchy' T-shirt.

He has encouraged people to wear it because it stated a sentiment, not defamation. It went viral on social media, after which Internal Security Operations Command forcibly admitted him to a psychiatric hospital. It was one of the causes of the 2020–2021 Thai protests' second wave protests, the largest demonstration since the 2014 Thai coup d'état, demanding he be released from involuntary hospitalization.

On 16 June 2020, he posted a photo on his Facebook account that went viral online. Before that, he proposed the idea of using the slogan 'I lost faith in the Monarchy' in 'The Royalists Marketplace', the monarchy-satire Facebook group by Pavin Chachavalpongpun. Many users were concerned for lese majeste law which had been used broadly and unpredictably. His photo received more than 4,000 comments from both sides of the issue. He re-entered activism again after Wanchalearm, a Thai political activist, was abducted by armed men in Phnom Penh on 4 June 2020.

On 19 June and 4 July, a Internal Security Operations Command officer and a local police officer came to his house to discuss with him.

On 5 July 2020, he showed the contract which signed him off of his family in his Facebook account for safety issues.
