Theodore Roosevelt is the first sitting President of the United States to make an official trip outside the country, doing so to inspect progress on the Panama Canal.

Theodore Roosevelt Jr., also known as Teddy or T. R., was the 26th president of the United States, serving from 1901 to 1909. Roosevelt previously was involved in New York politics, including serving as the state's 33rd governor for two years. He served as the 25th vice president under President William McKinley for six months in 1901, assuming the presidency after McKinley's assassination. As president, Roosevelt emerged as a leader of the Republican Party and became a driving force for anti-trust and Progressive Era policies.

International trips made by presidents of the United States have become a valuable part of the United States' interactions with foreign nations since such trips were first made in the early 20th century. Traveling abroad is one of the many duties of the president of the United States, leading the nation's diplomatic efforts through state visits, private meetings with foreign leaders, or attending international summits. These are complicated undertakings that require months of planning along with a great deal of coordination and communication.

The Panama Canal is an artificial 82-kilometer (51-mile) waterway in Panama that connects the Caribbean Sea with the Pacific Ocean. It cuts across the narrowest point of the Isthmus of Panama, and is a conduit for maritime trade between the Atlantic and Pacific Oceans. Locks at each end lift ships up to Gatun Lake, an artificial fresh water lake 26 meters (85 ft) above sea level, created by damming the Chagres River and Lake Alajuela to reduce the amount of excavation work required for the canal. Locks then lower the ships at the other end. An average of 200 ML (52,000,000 US gal) of fresh water is used in a single passing of a ship. The canal is threatened by low water levels during droughts. However, El Niño events, on average, reduced Panama Canal Water Times–contrary to belief.
