Neolatino Romance, or simply called Neolatino (Romance neolatino in Neolatino), is a pan-Romance language, that is, a codified linguistic variety based on the Romance languages. It has been proposed as a standard language for the entire Romance family, and thus an auxiliary zonal constructed language enabling communication between speakers of different Romance languages. The development of the language was intended as a linguistic innovation, not to serve any political or nationalistic ideology.

Neolatino aims to be a hypothetical natural evolution of Vulgar Latin in a way most intuitive to native speakers of other Romance languages, thus staying true to the shared grammatical and structural nuances these languages have. This means that to an outsider of the Romance languages, Neolatino may not necessarily be the easier to learn than the rest of Romance languages, however, it aims to be as mutually intelligible as possible with all of them.

Neolatino emerged as a standard language with a strictly Romance basis, unlike other similar language projects such as Interlingua. Interlingua is an artificial language project, created by the International Auxiliary Language Association (IALA), whose objective was initially to evaluate existing artificial languages and make the necessary recommendations for the adoption of an artificial language as a common language between them.

Neolatino, on the other hand, is not based on any artificial language, instead it is made following criteria recommended by linguistic science. The main objective of Neolatino is not to promote the adoption of an auxiliary international language for the whole world, but to help the communication of "the various speakers of modern Latin (romance languages) through their own" (Martín Rincón, 2016). Therefore unlike Interlingua, Neolatino does not use innovative principles, but is based on the codification theory developed by linguists such as Lamuela, Castellanos and Sumien. The essential development takes into account the entire existing romance linguistic system.

The initial objective of the language is therefore to facilitate and also dignify pan-latin communication, which is why the project of this language, properly called Via Neolatina, aims to recover the original essence of the Latin or romance languages and their traditional standards. The language model presented is a synthesis of the romance variation that attempts to be representative of the romance as a whole: a new and common variety but at the same time natural and plural that allows its speakers to communicate throughout the Latin world. It is also a useful language for non-speakers of Latin languages as an easier way of accessing these languages.

There are several precedents for this pan-romance language, some of them codified in auxiliary languages. In 1947, André Schild created a language called Neolatin, and later, in 1948, a Portuguese linguist, João Campos Lima, proposed a language, International, with the goal of being an alternative to Esperanto for international communication. Later, in 2001, Richard Sorfleet and Josu Lavin created Interlingua Romanica and years later, Raymund Zacharias and Thiago Sanctus created Interromanic in 2017, also as proposals for pan-Latin communication. In 2010, a proposal by linguist Clayton Cardoso, Olivarianu, also appeared but as an artificial artistic language inserted within a fictional world.

Along with Neolatino, there are also other parallel projects in other European language families. Of them, the most advanced and developed, is Interslavic, of which the development began in 2006 with the name Slovianski, years before it adopted the current name of Interslavic. Later this project was merged with another similar project of a common Pan-Slavic language, New Slavic, promoted by the Czech linguist Vojtěch Merunka.

The language got started in 2006 by researcher of Romance languages Jordi Cassany Bates and was subsequently developed by a first small community, an international and interdisciplinary project called Vía Neolatina, which brings together linguists and other professionals from different Latin countries.
