Jamaican Blue Mountain Coffee or Jamaica Blue Mountain Coffee is a classification of coffee grown in the Blue Mountains of Jamaica. The best lots of Blue Mountain coffee are noted for their mild flavour and lack of bitterness. Over the past few decades, this coffee has developed a reputation that has made it one of the most expensive and sought-after coffees in the world. Over 80% of all Jamaican Blue Mountain Coffee is exported to Japan. In addition to its use for brewed coffee, the beans are the flavor base of Tia Maria coffee liqueur.

Jamaican Blue Mountain Coffee is a globally protected certification mark, meaning only coffee certified by the Coffee Industry Board of Jamaica can be labeled as such. It comes from a recognised growing region in the Blue Mountain region of Jamaica, and its cultivation is monitored by the Coffee Industry Board of Jamaica.

The Blue Mountains are generally located between Kingston to the south and Port Antonio to the north. Rising to 2,300 metres (7,500 ft), they are some of the highest mountains in the Caribbean. The climate of the region is cool and misty with high rainfall. The soil is rich, with excellent drainage. This combination of climate and soil is considered ideal for coffee.
