Port Mansfield is a small community in Willacy County, Texas, United States. It is known as a census-designated place (CDP). This means it's a special area defined by the government for counting people. In 2020, about 319 people lived there.

Where is Port Mansfield?

Port Mansfield is located at 26°33′20″N 97°25′52″W / 26.55556°N 97.43111°W / 26.55556; -97.43111. It covers a total area of about 5.7 square miles (14.8 square kilometers). Most of this area is land, but about 0.5 square miles (1.3 square kilometers) is water.

A special channel connects Port Mansfield to the Intracoastal Waterway. This waterway is like a highway for boats along the coast. The channel also leads to the Gulf of Mexico. It cuts through Padre Island, which is a long, thin island. This cut is called the Port Mansfield Channel.

The channel needs to be kept deep for boats to pass easily. Sometimes, sand builds up and makes it shallow. This is called "shoaling." The channel was made deeper in 2009-2010. It was also dredged again in 2021. Now, it is 16–20 feet deep. This helps many boats use the channel safely.
