The Houston Livestock Show and Rodeo is the largest livestock exhibition and rodeo in the world. It was originally created to promote livestock production and agriculture in Texas, providing a space for farmers and ranchers to showcase their work. Over time, the event has grown from a small regional exhibition into one of the largest cultural and economic events in the United States. It includes one of the richest regular-season professional rodeo events. It has been held at NRG Stadium in Houston, Texas, since 2003, with the exception of 2021 due to the effects of the COVID-19 pandemic. It was previously held at the Astrodome.
