纽芬兰与拉布拉多省（英语：Newfoundland and Labrador，法语：Terre-Neuve-et-Labrador）是加拿大的十个省之一。纽芬兰与拉布拉多省由两部分组成：位于北美大陆以东的纽芬兰岛和附近岛屿，以及位于大陆东岸，与纽芬兰岛隔海相望的拉布拉多地区及其附属岛屿。

该省于1949年3月31日以「纽芬兰」的名称加入加拿大联邦，是最后一个加入联邦的省份。但从1964年起，省政府开始称呼自己为「纽芬兰与拉布拉多」政府。加拿大政府于2001年12月6日修改宪法，将省份的名字正式由「纽芬兰」改为「纽芬兰与拉布拉多」。

Newfoundland and Labrador (/njuːfənˈlænd ænd ˈlæbrədɔːr/, French:Terre-Neuve-et-Labrador, Irish: Talamh an Éisc) is the most easterly province of Canada. Situated in the country's Atlantic region, it comprises the island of Newfoundland and mainland Labrador to the northwest, with a combined area of 405,212 square kilometres (156,500 sq mi). In 2013, the province's population was estimated at 526,702. About 92% of the province's population lives on the island of Newfoundland (and its neighbouring smaller islands), of whom more than half live on the Avalon Peninsula. The province is Canada's most linguistically homogeneous, with 97.6% of residents reporting English (Newfoundland English) as their mother tongue in the 2006 census. Historically, Newfoundland was also home to unique varieties of French and Irish, as well as the extinct Beothuk language. In Labrador, local dialects of Innu-aimun and Inuktitut are also spoken.
