In [[coding theory]], a '''block code''' is any member of the large and important family of [[Channel coding|error-correcting codes]]j that encode data in blocks.

There is a vast number of examples for block codes, many of which have a wide range of practical applications. Block codes are conceptually useful because they allow coding theorists, [[mathematics|mathematicians]], and [[computer science|computer scientists]] to study the limitations of ''all'' block codes in a unified way.

Such limitations often take the form of ''bounds'' that relate different parameters of the block code to each other, such as its rate and its ability to detect and correct errors.
