Samran Rat (Thai: สำราญราษฎร์, pronounced [sǎm.rāːn râːt]), popularly known as Pratu Phi (ประตูผี, [prā.tūː pʰǐː]), is a historic neighbourhood in Bangkok.

The neighbourhood's better known restaurants include Jay Fai, which received one Michelin Guide star in 2017, and Thipsamai, which is famous for pad thai.

[5] Samran Rat is considered to be the central part indented to the east of the Bangkok's old town zone or Rattanakosin Island.

From the intersection, Bamrung Mueang road crosses the nearby Sommot Amonmak bridge into Pom Prap Sattru Phai district's Ban Bat subdistrict.

The point is known by this name because it used to be the location of the Special Bangkok Metropolitan Prison (ruan cham in Thai), built by the order of King Chulalongkorn (Rama V) in 1889.
