Tilleke & Gibbins is a regional law firm in Southeast Asia, with offices in Bangkok, Hanoi, Ho Chi Minh City, Jakarta, Vientiane, Phnom Penh, and Yangon. The firm's core practices are commercial transactions, mergers and acquisitions, dispute resolution, litigation, and intellectual property law.
 In 1890, William Alfred Tilleke, a Ceylonese solicitor, began a new practice in Siam (now Thailand). In 1894, Tilleke gained recognition when he successfully defended Phra Yot Muang Kwang, a Thai provincial governor, who had been accused of murdering a French military officer. In the face of colonial pressure by the French and before a French Court conducted in Thailand, Tilleke exonerated Phra Yot through affirmative evidence and all seven judges presiding returned a "Not Guilty" verdict.
 Ralph Gibbins, an Englishman, partnered with Tilleke in 1902, and the firm adopted the name, Tilleke & Gibbins. Later, Ralph became a legal adviser in the Siamese Ministry of Justice, before serving as a judge of the International Court in 1916.
 Samuel Brighouse and Reginald Atkinson led the firm from 1911 until Thailand’s involvement in World War II in 1941. During the war, the firm ceased operations. Some of the company documents were safeguarded by Ina Jorgensen, the former secretary of one of the firm's partners, Victor Jaques, who had fled abroad. In 1946, Mr. Jaques reestablished the firm as the sole partner remaining after the war had ended.
 In 1951, Albert Lyman purchased the firm—minus its trademark and intellectual property work, which had been given to Jorgensen—from Victor Jaques for $2,500. Mr. Lyman and his wife, Freda, ran the firm with a Thai partner, Rojvit Periera. The Lymans’ son, David, joined the firm in 1967 and took over Tilleke & Gibbins’ operations after his father’s death in 1984. In addition to being Chairman of the firm, David also acts as the firm's Chief Values Officer.
 Darani Vachanavuttivong and Tiziana Suchartikul are the Managing Partners of the firm.
