Uropi is a constructed language which was created by Joël Landais, a French English teacher. Uropi is a synthesis of European languages, explicitly based on the common Indo-European roots and aims at being used as an international auxiliary language for Europe and thus contributing to building a European identity.

Uropi was begun in 1986; since then, it has undergone certain modifications; its vocabulary keeps growing (the French-Uropi dictionary has over 10,000 words).

Uropi became known in Europe in the early 1990s.

After studying languages at the University of Orléans, then at the Sorbonne and at the École Normale Supérieure in Paris, Joël Landais obtained the Agrégation diploma in English. He speaks French, English, Italian, Spanish, German and has a working knowledge of modern Greek and Russian. Today, he teaches English in a Chartres college. Parallel to his training as a linguist, his travels throughout Europe, Senegal, the Maghreb, Egypt, Mexico, former USSR, Vietnam and the West Indies, together with a passion for languages, led him to create Uropi.

The Uropi alphabet has 26 letters, the 26 letters of the ISO Basic Latin alphabet minus q, plus the letter ʒ, which comes from the International Phonetic Alphabet. Each letter corresponds to a sound and each sound to a letter.

All consonants are pronounced as in English except

The vowels a, e, i, o, u are pronounced as in Italian or Spanish: casa, solo, vino, luna, pepe. Stress normally falls on the main root. For example, in apkebo = to behead, the stress falls on keb = head. However some suffixes (such as -èl indicating an instrument) and the ending -ì for the past are always stressed; when two or more suffixes are combined, the stress always falls on the penultimate suffix (the last but one). The stress is marked with a written accent (à è ì ò ù) on the stressed vowel when it falls on the last syllable. For example: kotèl, perì, fotò, menù = "knife, carried, photo, menu".

Uropi roots can be divided into three categories:
