"I was an amateur boxer in my youth, and I brought that fighting spirit with me to Washington", Hatch said in a video posted online.
Local media said U.S. President Donald Trump had lobbied Hatch to stay in the Senate in a bid to block Romney from running.
Romney maintains residence in Utah and was the president and CEO of the Salt Lake City Olympic Committee before going on to serve as governor of MA and challenge Barack Obama as the Republican nominee in the 2012 presidential election.
Hatch also served as chairman of the Senate Judiciary Committee and was at the center of numerous biggest confirmation battles.
His decision comes after The Salt Lake Tribune, Utah's largest newspaper, published a scathing Christmas Day editorial calling on him to leave the seat. He chairs the powerful Senate Finance Committee and was a major force in getting a tax overhaul through Congress and signed into law in December. "He has been a tremendous supporter, and I will never forget the (beyond kind) statements he has made about me as President", Trump tweeted Tuesday.
Bachmann, a former Tea Party star, would likely run a campaign more in line with Trump's branding: In a recent interview with Jim Bakker, she predicted that "the swamp" would push back against her candidacy, an allusion to Trump's anti-Washington tagline, "drain the swamp".
Mr Romney has been quiet about his plans and views of late.
The 83-year-old has been publicly weighing whether or not to step down.
The longest-serving Senate Republican with seven terms under his belt, he was first elected in 1976.
Sanders said that Trump "has the greatest and deepest amount of respect for Senator Hatch and appreciated the role he played in the tax talks".
Romney thanked Hatch in a statement on Facebook and said Hatch "has represented the interests of Utah with distinction and honour".
"Congratulations to Senator Orrin Hatch on an absolutely incredible career", Trump tweeted Tuesday evening. Sherrod Brown of OH after Brown said Republican tax cuts were aimed at helping the rich. During his time on the committee, the Senate has confirmed almost 1,900 federal judges, a majority of all federal judges that have served. Should they decide to run, their presence might be a welcome bit of nostalgia to GOP voters worn out by Trump's presidency; but they could also provide an unwelcome flashback. He withdrew from the race after only winning 1 percent of the vote in the Iowa caucuses and then endorsed George W. Bush.
