The phrase cup of Joe is a colloquial and informal term for a serving of coffee. It’s commonly used in casual conversation and refers to a cup of coffee in everyday language. While we do not know precisely where the term arose there are a few leading theories.
Why Is Coffee Called a Cup of Joe?: Sipping On A Few Theories
Your Average Joe
During World War I, the U.S. Navy faced the challenge of providing its sailors with a hot and energizing beverage. Coffee quickly became the beverage of choice, as it was practical and efficient to serve on board naval vessels. Coffee not only helped to keep the sailors awake during long shifts but also provided some warmth and comfort in the often harsh conditions at sea.
The name Joe in the phrase a cup of Joe likely derives from its colloquial use as a generic or common name for an average person. This usage can be traced back to the late 19th and early 20th centuries. A similar term, Holy Joe, was used to denote a chaplain or religious leader, frequently within the military or naval environment.
When sailors were served coffee, it became known as a cup of Joe, emphasizing that it was a standard, everyday drink for the average sailor.
The term a cup of Joe carries a hint of irony. Sailors, renowned for their humor and inclination for clever language, may have playfully coined the phrase with a touch of sarcasm. It’s almost like they were quipping: here’s your plain and simple black coffee, just as any Joe would prefer. This expression probably developed among naval circles before gaining popularity among the general public.
Josephus Daniels Theory
Josephus Daniels was appointed Secretary of the Navy in 1913, and during his tenure, he implemented a series of significant reforms in the U.S. Navy. One of the most well known reforms was his decision to ban the consumption of alcohol on naval ships. This prohibition was part of a broader effort to improve discipline and morale among sailors.
With the ban on alcohol, coffee quickly became the beverage of choice for sailors on U.S. Navy ships. Coffee was practical to serve on board ships and helped keep sailors alert during their duties. As a result, coffee gained popularity as the go to drink in the Navy.
According to this theory, the phrase a cup of Joe emerged as a humorous or ironic reference to Josephus Daniels himself. Sailors, known for their penchant for nicknames and wordplay, playfully associated the Secretary of the Navy with the beverage that had become so integral to their daily lives. By calling coffee a cup of Joe, they may have been highlighting the fact that under Daniels’ leadership, coffee had become the dominant drink in the Navy. The term likely began within naval circles but eventually made its way into civilian slang.
The Legacy Of Joe Martinson Coffee
Joe Martinson founded Martinson Coffee in 1898 in New York City. The brand gained popularity for its quality coffee beans and blends, becoming one of the prominent coffee companies in the United States. Martinson Coffee was known for its commitment to delivering consumers a consistently good morning cup of coffee.
According to this theory, the phrase a cup of Joe may have emerged as a casual way to refer to coffee due to the widespread recognition of the Martinson Coffee brand. People might have begun using a cup of Joe to denote any morning cup of coffee, much like saying a Coke to refer to any carbonated soft drink, regardless of brand.
Java And Mocha: Slang Fusion
Some language experts suggest that the term Joe may have roots in two other coffee related words: Java and Mocha. During the 1930s, Jamoke was a popular slang term for coffee, blending the terms mocha, denoting a type of coffee, and java, which referred to coffee in general. This combination, Jamoke, captured the essence of the coffee culture of that era.
Linguists propose that over time, the term Jamoke might have been shortened to simply Joe. This process of abbreviation is common in the evolution of slang terms, as words are often simplified or clipped for convenience and ease of use. Today, coffee enthusiasts still encounter the terms mocha and java, which are reminiscent of this historical coffee jargon.

Many idiomatic expressions have obscure or unpredictable origins because they often arise from informal and spontaneous language use.
