Perhaps no other city in America is more famous for being home to the mega-rich than Dallas, Texas. It is not just the oil industry that has helped many in the area amass their fortunes. The lack of state income tax in Texas helps make it an attractive place to call home for many billionaires.

Here are the five richest billionaires living in Dallas, Texas, according to the Forbes 400 list for 2019, a ranking of the nation's richest 400 billionaires by net worth.

1. Alice Walton

Alice Walton is the daughter of Sam Walton, the founder of Wal-Mart back in 1962. Alice has certainly benefited from the Wal-Mart effect and now has an estimated net worth of $51.4 billion, Alice Walton is the richest person in Texas. Unlike her brothers Rob and Jim, Alice is not involved in the company and focuses on her extensive art collection, which is worth more than $500 million. She opened the Crystal Bridges Art Museum in her hometown of Bentonville, Arkansas, in 2013. The museum features a Frank Lloyd Wright-designed home that she moved from New Jersey, as well as works by Andy Warhol, Norman Rockwell, and Georgia O'Keeffe.

Walton put her two massive Dallas-area ranches on the market in 2015 for a combined asking price of $48.5 million. Featuring over 5,872 acres of rolling hills, river frontage, and horse ranching facilities, the land also has extensive oil and gas reserves.
