調合（ちょうごう、英語: Concoction）とは、医薬品、食品、またはその他の物質を多くの材料から準備する過程であり、またその過程の結果である。

歴史的に、この言葉は消化を指しており、アリストテレスが提唱した理論では、消化は身体の熱が物質に作用し、それを成熟させて熟させる結果であるとされた。

The term later came to refer to liquid broths, cocktails and potions which are similarly formed by heating or blending multiple ingredients. Concoctions that were made in apothecaries, or as used in traditional medicine, rather than nourishment or pleasure (in which case it would be cookery or cuisine). In a medical context, such concoctions have largely been superseded by modern medicine.

In modern usage, the term may refer more loosely to any mixture of various ingredients, including soups and cocktails, or abstract ingredients, such as design elements in architecture or fashion, or an elaborate excuse. In such uses, the term often retains a connotation that the mixture is strange, unusual, or elaborate.
