A Latin Dictionary is a popular English-language lexicographical work of the Latin language, published by Harper and Brothers of New York in 1879 and printed simultaneously in the United Kingdom by Oxford University Press.

The Oxford Latin Dictionary is the standard English lexicon of Classical Latin, compiled from sources written before AD 200. Begun in 1933, it was published in fascicles between 1968 and 1982; a lightly revised second edition was released in 2012.
