What country is listed as Pad Thai's place of origin?

Pad Thai’s listed place of origin is Thailand.

Although rice noodles and stir-frying have Chinese roots elsewhere in Southeast Asia, the modern dish called Pad Thai was developed and popularized in Thailand. Its name means “Thai-style stir-fry,” and its characteristic combination of sweet, sour, salty, and spicy flavors reflects Thai culinary preferences.

The dish is often linked to Thailand’s mid-20th-century nation-building period. During World War II, rice shortages and concerns about domestic rice consumption helped encourage noodle eating. Government promotion of rice noodles contributed to Pad Thai’s modern national profile, though historians and food writers also discuss the influence of Thai-Chinese cooks.

That background explains why Cambodia, Malaysia, and Vietnam can seem plausible alternatives: each has related Chinese-influenced noodle traditions. Their analogous dishes are not the same as the Thai dish identified as Pad Thai.
