Din Daeng (Thai: ดินแดง, pronounced [dīn dɛ̄ːŋ]) is one of the 50 districts (khet) of Bangkok, Thailand. Its neighbours, clockwise from north, are Chatuchak, Huai Khwang, Ratchathewi, and Phaya Thai.

The district was created in 1993, when the eastern part of Phaya Thai was split off to form a new district. The district is highly populated partly due to the concentration of apartments built by National Housing Authority. They are along Din Daeng and Pracha Songkhro Roads.

Its name literally means red soil, it comes from a dirt road in the same name that constructed during the government of Field Marshal P. Pibulsongkram in 1940s, which looks red in colour. Locals soon used the term Din Daeng to call the area. Today, it is better known as Din Daeng Road.

According to Thailand's Pollution Control Department (PCD)^[2] Din Daeng is the noisiest district in the city. It suffers from noise pollution on the order of an average daily noise level of 71.6 to 81.6 A-weighted decibels. A-weighting is commonly used for the measurement of environmental and industrial noise, as well as for assessing potential hearing damage. The safe limit is no more than 70 decibels on average in a 24-hour period. The PCD attributes the noise to vehicular traffic.

Sites in Thon Buri District and Huai Khwang District were named the second and third most noise polluted.^[3]

The district is divided into two sub-districts (khwaeng).
