Greggory D. "Gregg" Hull is an American politician and businessman who has served as mayor of Rio Rancho, New Mexico, since 2014. He is the longest-serving mayor in Rio Rancho history. He is running for Governor of New Mexico in the 2026 election as a Republican.
Hull has lived in New Mexico for more than 35 years and was a small businessman in Rio Rancho before serving as mayor.
Hull was first elected in 2014 in a runoff election and was re-elected in both 2018 and 2022. Rio Rancho, the state's third-largest city, was the fastest-growing city in New Mexico while he was mayor. While he was mayor, Hull doubled the city's police budget and pursued pro-business economic development policies. In November 2025, he announced he would not seek a fourth term in order to focus on his gubernatorial campaign.
In April 2025, Hull became the first Republican to signal his intention to enter the race for governor. After a statewide listening tour over the following months, he officially launched his campaign in October 2025, running on a platform focusing on public safety and economic growth.
In March 2026, the GOP pre-primary in Ruidoso gave Hull the clear majority, with many observers declaring him the 'favorite' for the Republican nomination.
Hull and his wife Carrie have been married for more than 25 years and have five children and eight grandchildren. They live in Rio Rancho.
