ASCII (kep. "American Standard Code for Information Interchange", BM: "Kod Piawai Amerika untuk Pertukaran Maklumat") adalah satu format yang lazim digunakan untuk fail teks dalam komputer dan internet. Kod ASCII telah dibangunkan oleh American National Standards Institute (ANSI).
Dalam fail yang menggunakan kod ASCII, setiap aksara (angka, abjad dan simbol khas) diwakili oleh sejumlah 7 bit nombor perduaan yang terdiri daripada rentetan tujuh '0' atau '1'. Ia melibatkan sejumlah 128 aksara biasa dengan tambahan 128 aksara lanjutan.
ASCII reserves the first 32 codes (numbers 0–31 decimal) for control characters: codes originally intended not to carry printable information, but rather to control devices (such as printers) that make use of ASCII, or to provide meta-information about data streams such as those stored on magnetic tape. For example, character 10 represents the "line feed" function (which causes a printer to advance its paper), and character 8 represents "backspace".
