A trigraph (from the , treîs, "three" and ?????, gráph?, "write") is a group of three letters used to represent a single sound or a combination of sounds that does not correspond to the written letters combined. For example, in the word schilling, the trigraph sch represents the voiceless postalveolar fricative , rather than the consonant cluster . In the word beautiful, the sequence eau is pronounced , and in the French word château it is pronounced . It is sometimes difficult to determine whether a sequence of letters in English is a trigraph, because of the complicating role of silent letters. There are few productive trigraphs in English; one is tch as in watch.

The trigraph sch is German, where it is equivalent to the English sh; like English sh, it is not regarded as an independent letter of the alphabet. In Hungarian, the trigraph dzs is treated as a distinct letter, with its own place in the alphabet. It is prononounced like an English "j" . The combination gli in Italian can also be a trigraph, representing the palatal lateral approximant before vowels other than i.

Although trigraphs are not uncommon in adaptations of the Latin alphabet, they are rare elsewhere. There are several in the Cyrillic alphabet, which for example uses five trigraphs and a tetragraph when writing the Kabardian language: ??? , ??? , ??? , ??? , ??? , and ???? . While most of these can be thought of as consonant + , the letters in ??? cannot be so separated: the ? has the negative meaning that ??? is not ejective, as ?? is . (See List of Cyrillic digraphs.)

Hangul has a single obsolete trigraph, ? , a theoretical form not actually found in any texts, which is the digraph ? plus a bottom circle used to derive the labio-dental series of consonants.

Japanese kana use trigraphs for Cy? sequences, as in ??? kyou 'today'; the ? is only pronounced after another .
