Niçard (Classical orthography), nissart/Niçart (Mistralian orthography, IPA: [niˈsaʀt]), niçois ( nee-SWAH, French: [niswa]), or nizzardo (Italian: [nitˈtsardo]) is the dialect that was historically spoken in the city of Nice, in France, and in all the area of the historical County of Nice. The affiliation of Niçard is debated: it is generally considered a subdialect of Provençal, itself a dialect of Occitan, while some scholars argue that the historical dialect spoken in Nice was more strictly Ligurian.

Most residents of Nice and its region no longer speak Niçard, and the very few who do are fully bilingual in French as Nissard has lost its function of a vehicular language since decades. Nonetheless, today there is a developing revival of the use of the language. Some local television news is presented in Niçard (with French subtitles) and street signs in the old town of Nice are written in the dialect as well as in French. The Niçard song Nissa La Bella is often regarded as the "anthem" of Nice.
