Loa Janan () is an administrative district (kecamatan) in Kutai Kartanegara Regency, East Kalimantan Province of Indonesia. It covers a land area of 644.20 km2, and had a population of 56,071 at the 2010 Census and 67,471 at the 2020 Census; the official estimate as at mid 2025 was 79,365. Its district seat is located at the village of Loa Janan Ulu.

Before 21 October 1987, the villages of Loa Buah, Loa Bakung, and Loa Janan Ilir were part of Loa Janan, but at that date these villages were transferred to the city of Samarinda. The former village of Loa Janan Ilir then later evolved into its own district within the city. There are claims that Loa Janan was originally part of Loa Kulu, nonetheless, much of the administrative history of East Kalimantan before 1969 remains unclear.
