Four Seasons Resort and Club Dallas at Las Colinas is a five-star golf resort in Texas, located in the hills of Irving, several miles northwest of downtown Dallas. It is operated by Four Seasons Hotels and Resorts and is the only AAA Five Diamond resort and club in Texas. 
The resort contains a 431-room hotel, two restaurants, lounge bars, a spa, and an array of leisure facilities, including a swimming pool, gym, tennis courts and two golf courses, featuring a Tournament Players Club course, TPC Las Colinas, that hosted the PGA Tour's annual AT&T Byron Nelson.
The Dallas Morning News reported on January 13, 2010, that the lenders have filed for foreclosure on the property, seeking repayment of a $183 million loan. 
The Four Seasons Resort and Club Dallas at Las Colinas is known for its golf facilities, which includes the TPC Las Colinas championship course that was designed by Jay Morrish in consultation with Byron Nelson and Ben Crenshaw. The course was constructed as a TPC stadium course, incorporating nine holes from the original Las Colinas Sports Club layout. Since it opened in 1983 (Crenshaw won the 1st event in 1983,   see wall of champions inside the sports club), it had been the venue for the PGA Tour's Byron Nelson event for 35 years, through 2017. 
Starting in 1994, the PGA Tour has also made use of the resort's second course, Cottonwood Valley, for the first two rounds of the Byron Nelson Championship in order to lessen the impact of weather delays. This course was also designed by Jay Morrish this time alongside renowned golf course architect Robert Trent Jones, Jr. 
The resort also includes the Byron Nelson Golf School, a driving range and other practice facilities.
