A vigil honouring those killed and wounded in Sunday's Florida nightclub shooting drew at least a dozen people to the front gate of the US Embassy.
Participants passed around white and yellow candles to light in memory of those killed.
"We are distraught by what happened in Orlando," said Paisarn Likhitpreechakul, the vigil's organiser. "We are looking for a way to express our condolences and solidarity with the people and government of the United States to raise awareness of problems of violence against the LGBT community."
US Ambassador Glyn T Davis came out to speak with the Thai LGBT activists and lit a candle.
Separately, the Royal Household Bureau released a message from His Majesty the King to President Barack Obama. The message expressed deepest sorrow. His Majesty said:
"The Queen and I are deeply distressed by reports of the brutal shooting at the nightclub in Orlando, resulting in senseless deaths and injuries of so many innocent people.
"We wish to express to Your Excellency and particularly the bereaved families our deep sympathy and condolences for their irreparable loss caused by this shocking incident."
