Chaophraya Aphaiphuthon ( ? - 1827), personal name Noi , was the Samuha Nayok or Prime Minister of Northern Siam from 1813 to 1827. He was a member of the Punyaratabandhu or Boonyarataphan family.

Noi was a son of Chaophraya Sithammathirat , whose personal name was Boonrot, who was the Minister of Palatial Affairs during the reigns of King Taksin and King Rama I. In 1785, during the Nine Armies' War, Noi's father Chaophraya Thamma Boonrot was stripped of his position due to a mismanagement during the war. His father was later restored to the position of Chaophraya Sithammathirat as the master of palace ceremonies. Noi's sister, Lady Pi, became a consort of Prince Itsarasunthon.

In 1809, King Rama I passed away and was succeeded by his son Prince Itsarasunthon as King Rama II. Noi, who was then holding the position of Phra Anuchitracha the leader of Right Royal Guard Regiment, found a mysterious written message in the courtyard of Dusit Maha Prasat Throne Hall. The message was about Prince Kasattranuchit, a son of King Taksin whose mother was a daughter of King Rama I, saying that Prince Kasattranuchit was plotting a rebellion.
