Nam chim or nam jim (, ) is Thai for "dipping sauce". It can refer to a wide variety of dipping sauces in Thai cuisine, with many of them a combination of salty, sweet, spicy and sour.

Nam chim tend to be more watery in consistency than nam phrik (Thai chili pastes). Although Sriracha sauce is commonly known as sot Sriracha in Thailand (sot is the Thai pronunciation of the English word sauce), it is sometimes called nam chim Sriracha or nam phrik Sriracha.

A more-or-less generic and basic nam chim is used for grilled or steamed seafood. This sauce contains garlic, fish sauce, sugar, lime juice, and bird's eye chilies. Variations on this basic recipe find their use as a dipping sauce with and as an integral part of many dishes. Many of the ingredients in a nam chim are finely chopped or pounded in a mortar and pestle or, non-traditionally, ground in a blender.

History
The history of nam chim can be traced back to the Ayutthaya period of Thailand's history. French diplomat Simon de la Loubère, who visited Siam during the mid-Ayutthaya period, described the use of plain sauces with spices, garlic, chibols, or sweet herbs, as well as a fermented shrimp paste called kapi, which was commonly used to enhance the flavor of dishes. Many types of nam chim used in different dishes are mentioned in various cookbooks, including "Maekrua Hua Pak" (1908–1909) by Mrs. Plian Passakornwong, and "Nang Suea Kap Khao Son Luklan Kap Pholmai Khong Wang Lae Khanom" (1876-1961) by Mrs. Kleep Mahitorn. These early dipping sauces evolved over time, with various regional variations and styles emerging, resulting in countless unique blends of flavors and ingredients found in today's nam chim.

Variants
Popular dipping sauces in Thailand are:
 Nam chim kai (), sweet chili sauce is a very common all-round chili dipping sauce with the consistency of a thick syrup. It is medium spicy and very sweet, normally referred to as "sweet Thai chili sauce" in English. It is often used as a dipping sauce for grilled chicken (kai yang). It can be used as a generic chili sauce for other dishes. It forms the base of a few other types of nam chim, such as nam chim thot man pla ("dipping sauce for deep-fried fish cakes").
 Nam chim chaeo (), using ground dry-roasted glutinous rice, this sauce is most often eaten with mu yang/mu ping (grilled pork) or kai yang (grilled chicken).
 Nam chim sate () is the Thai version of peanut sauce; it is eaten with Thai satay.
 Achat () is the Thai version of the Malay/Indonesian acar timun (cucumber pickles). The Thai variety consists of fresh chopped cucumber, spring onion and chili, mixed with vinegar. It is usually served with nam chim sate as a dip for satay.
 Nam chim suki  () is eaten with Thai suki (the Thai version of the Chinese hot pot) and Mu kratha. The main ingredients are chili sauce, chili, garlic and sesame seeds.
 Nam chim taochiao (), containing yellow soybean paste (taochiao), is eaten with khao man kai
 Nam chim thale () — a basic dipping sauce made with garlic, fish sauce, lime juice, sugar and chilis — is usually eaten with grilled or steamed seafood.
