The naming of the station was heavily debated online in June 2022, as some considered the name's similarity to that of Kelantan state in Malaysia inappropriate. The station's name however was retained due to historical reasons. "Khlong Kalantan" was a canal constructed during the reign of King Rama III as a link between Khlong Saen Saep and Khlong Phra Khanong to supplement troop transport for the Siamese-Vietnamese wars. The workers were from the tributary Patani Kingdom which was ruled by the Kelantanese dynasty, and thus the canal was named 'Kalantan' canal, reflective of those who dug it. Nearby infrastructure also bear the name 'Kalantan' such as Khlong Kalantan School. The name later would get shortened from 'Khlong Kalantan' to simply 'Khlong Tan'.
