Latino sine flexione (Latin without inflections) is an auxiliary language invented by the mathematician Giuseppe Peano in 1903. The language itself is simplified version of Latin, and retains its vocabulary. The justification for Latino sine flexione was given by Peano's article, "De Latino sine Flexione, Lingua Auxiliare Internationale". The article argued that auxiliary languages are unnecessary, since Latin is already established as the world's international language. The article was written in classical Latin, although it gradually dropped its inflections until there were none. It has been called "interlingua" but should not be confused with the more common conlang Interlingua, which later replaced Latino sine flexione.

Though Peano removed the inflections of Latin from nouns and adjectives he did not do away entirely with grammatical gender, permitting the option of a feminine ending for occupations. The gender of animals is immutable. The forms of nouns all end with a vowel and are taken from the ablative case, but as this was not listed in most Latin dictionaries, he gave the rule for its derivation from the genitive case, which is. Though he tries to do away with plurals, when they are needed an "s" is added. Verbs have few inflections of conjugation; tenses and moods are instead indicated by verb adjuncts. The result is a change to a positional language.
