So, how many cities are packed into Dallas County, Texas, and what makes them tick? If you’ve ever wondered, “How many cities are in Dallas, TX?” get ready for a deep dive into this urban sprawl.

Quick Take: The Numbers Game

Dallas County is home to 10 fully incorporated cities and 3 incorporated towns, plus 18 cities that partially lie within Dallas County and stretch into neighboring counties. That means you’re looking at over 30 municipalities tied to Dallas County in one way or another.

What’s Dallas County?

Before we get into the cities themselves, some context: Dallas County is the second most populous county in Texas, with over 2.6 million residents as of the 2020 U.S. Census. It spans about 871 square miles and is the economic, cultural, and transportation hub of North Texas.

If the county were a person, it would be the one who never sleeps, thanks to the Dallas/Fort Worth International Airport and a sprawling light rail system operated by DART (Dallas Area Rapid Transit), connecting the cities within.
