Sichuanese, also known as Sichuanese Mandarin or Sichuanese Sinitic, is a variety of Mandarin Chinese spoken in the Sichuan province of China. It is part of the larger Mandarin Chinese language group, which is itself a branch of the Sino-Tibetan language family.

Sichuanese is characterised by distinctive phonological features, vocabulary, and grammar that set it apart from Standard Mandarin. While Standard Mandarin is the official language of China, regional varieties like Sichuanese are spoken in daily life, especially in informal and local contexts.

Efforts have been made to preserve and promote Sichuanese culture and language, recognising their importance to the cultural identity of the region. However, like many regional varieties of Chinese, Sichuanese faces challenges from the widespread use of Standard Mandarin, especially in formal education, government, and media. There is ongoing debate and discussion about the balance between promoting linguistic diversity and maintaining a unified national language policy in China.
