The America the Beautiful quarters (sometimes abbreviated ATB quarters) were a series of fifty-six 25-cent pieces (quarters) issued by the United States Mint, which began in 2010 and lasted until 2021. The obverse (front) of all the coins depicts George Washington in a modified version of the portrait used for the original 1932 Washington quarter. There were five new reverse (back) designs each year (one in 2021), each commemorating a national natural or historic site such as national parks, national historic sites, or national forests – one from each state, the federal district, and each territory. The program was authorized by the America's Beautiful National Parks Quarter Dollar Coin Act of 2008 (Pub. L. 110–456 (text) (PDF).

Quarters were issued with reverse designs commemorating national parks and sites in the order of which that park or site was deemed a national site. The quarters from three states depict parks or sites that were previously portrayed on the state quarters (Grand Canyon in Arizona, Yosemite in California, and Mount Rushmore in South Dakota). While they depict the same sites, they bear new designs.

In 2020, the obverses of the quarters struck at West Point also include a privy mark. The privy design features the text "V75", celebrating the 75th anniversary of the end of World War II inside an outline of the Rainbow Pool at the World War II Memorial in Washington, DC.

Over the course of the series, four mint marks were used on the America the Beautiful quarters. Quarters produced at the Philadelphia and Denver Mints feature the P and D mint marks respectively.

In 2010 and 2011, the San Francisco Mint (S mint mark) produced quarters exclusively for the annual Proof Set. In 2012, San Francisco started producing America the Beautiful quarters in the standard circulation finish of the P and D quarters for sale to collectors.

On April 2, 2019, the United States Mint announced that the West Point Mint would release 10,000,000 quarters (2,000,000 of each design released that year) with the "W" mint mark. This was the first time the mint mark appeared on a circulating coin. The quarters were mixed into uncirculated bags and rolls of the quarters to stimulate public interest in coin collecting.

Beginning with the El Yunque (Puerto Rico) design in the America the Beautiful Quarters Program, the U.S. Mint began selling (at a premium) uncirculated 40-coin rolls and 100-coin bags of quarters with the San Francisco mint mark. These coins were not included in the 2012 uncirculated sets or the three-coin ATB quarter sets (which consisted of an uncirculated "P" and "D" and proof "S" specimen) and no "S" mint-marked quarters are being released into circulation, so that mintages will be determined solely by direct demand for the "S" mint-marked coins. As of January 2013 initial United States Mint sales figures indicated that between 1.3 million and 1.6 million of each 2012 design had been struck at the San Francisco Mint, close to the announced mintage of 1.4 million for each design. Direct U.S. Mint sales of rolls and bags of uncirculated business strike coins continued with the 2013 America the Beautiful quarter issues, with actual quantities again determined by customer orders. The mintages of the uncirculated "S" quarters are considerably lower than that of the "P" and "D" mint-marked coins and are comparable to the 1996-W Roosevelt Dime (also not issued for circulation), which sells in the neighborhood of $20 each in an average grade. As of 2019, uncirculated "S" quarters can be obtained from dealers for about three to four times their face value.
