Sam Yan (Thai: สามย่าน, pronounced [sǎːm jâːn]) is the name of an intersection and its nearby neighbourhood in Bangkok, Thailand.

They originally engaged in trading used car parts that expanded along Rama IV Road from Sieng Kong or Talat Noi in Chinatown area.

[2][3][4] The university began developing the area's real estate for rent in 1963, and until the late 2000s, the neighbourhood consisted of various shophouses which held many well-known restaurants.

At the heart of the neighbourhood was Sam Yan Market, a permanent foodstuff marketplace established in 1965, whose cheap upstairs restaurants were popular with students.

Sam Yan Market was relocated a few hundred metres away to the northwest nearer Suphachalasai Stadium, and most shop owners followed.
