A new record for the Flora of Thailand is reported, Lithocarpus gigantophyllus. The new record was discovered among Thai herbarium specimens during the Fagaceae Identification and Red Listing workshop, organised by BGCI and Pha Tad Ke Botanical Garden in Luang Prabang, Laos. For this species we provide colour images and a description of the collecting locality together with a morphological analysis and an updated key for the Lithocarpus species found in Thailand. The species is unique for Thailand in having a combination of large leaves, infructescences with variably developed cupules arranged in clumps, depressed, turbinate acorns with broad scars and golden silky hairs inside the cupules.
