United States of America
The United States of America (United States, US, USA, the States, or America) was a large country in the North American continent on Earth. The capital was Washington, DC. Its primary language was English. (; )

The United States was a representative  founded in the 18th century, and played a significant role in the history of Earth prior to the world's unification. The people and culture of the United States were known as American. The federal government was known as the United States Government.

According to Doctor Paul Stubbs, baseball, centuries ago, "was the beloved national pastime of the Americas." ()

When the Michael Sullivan character of the Fair Haven program was beamed to the bridge of the , he described at one point how he had a relative that had gone to America, what he thought previously was one of the strangest places. ()

On the planet Omega IV, there was a parallel United States. This country was mentioned in Article I of their Constitution. ()

The United States of America was the location of some of Earth's most important and largest cities. Among these include New York City, New Orleans, Los Angeles, and San Francisco which would later become the location of Starfleet Headquarters.

The capital of the United States was Washington which was located in the District of Columbia, with the city of Washington and the District having exactly the same boundaries.

Background information 
Retroactive continuity: 20th century-era maps of the northern hemisphere Pacific region were stored in the  library computer in 2254. One map depicted the east coast of Asia's USSR nation and Alaska on the west coast of North America. Another map depicted the globe from the point of view of the Arctic Circle, showing the same region. These maps were among the materials viewed by the Talosians when they scanned the Enterprise computer. ()

Retroactive continuity: A map of the mid-Atlantic coast of the United States depicting the location of Washington, DC was downloaded from the  library computer by the Talosians in 2254. () This map was from educational texts available at the time of filming, .

In , Data states that the American flag with 52 stars determines the date of the Charybdis wreckage as originating between 2033 and 2079. From this it can be inferred that:
In 2033 the number of states in the US became 52
In 2079 the United States could have:
Added one or more states
Seceded or dissolved one or more states
Changed or modified the flag format
Ceased to exist

Ominously, 2079 was also mentioned in . It was the year of Q's court, defined by the time period post-atomic horror. Evidence from  and  indicate that parts of the planet, particularly Zefram Cochrane's area (Montana), were improving due to contact with the Vulcans.

A San Francisco address seen on-screen in  included "USA, Earth", suggesting that "USA" exists at least as a political/geographic designation in 2154. Also, during the NX-01 holoprogram seen in , Malcolm Reed tells Chef, played by Commander Riker, that "his countrymen" might describe Florida native Trip as a hick, suggesting the US was still intact when the Federation was founded in 2161. Certainly, James T. Kirk was well-versed in, and quite passionate about, United States documents and customs, so much so that he was able to give an impassioned, memorized recital of the Preamble to the Constitution to the Yangs of planet Omega IV in . Samuel T. Cogley referenced the Constitution to the court at Kirk's trial in , so the United States obviously looms large in the minds of Starfleet officers in the 23rd century. There are many references to individual American states throughout the run of all the series, but it is not specified if the references are solely geographical or if they retain a political implication as well.

The 52-star flag seen in  is unusual in that the field of stars rests on a red stripe instead of a white stripe. The 15-star "Star-Spangled Banner" flown over Fort McHenry during the War of 1812 was the last such flag, and since then, all flags (then returning to 13 instead of 15 stripes) have had the familiar arrangement of the field being to the left of the first seven stripes and resting on the 8th, a white. This was probably an error in the art department, but being a future flag, it could be "official," with the government making that change for one reason or another, though it seems unlikely.

 makes it clear that the war there occurred generations ago, and that post war the lifespan lengthened to about a thousand years. This places the war well before 1200 AD, meaning that Omega IV had the United States of America, the Pledge of Allegiance, and the United States Constitution several centuries (at least) before Earth; on the other hand, in the non-canon novel Forgotten History, the "American" elements of Yang society are not indigenous, but were left behind by a passing ECS freighter in the 2140s.

The German map of the continental United States from the episodes  and  includes a combination of real and fictitious locations. Alongside Springfield, IL and Annapolis, MD – both of which are the capital city of their respective states – there is Crossroads, MO and Sun Valley, AL.
