The Navy Electronics Laboratory oceanographic research ship USS Rexburg was named for the city.

The city gained attention after the murders of Tylee Ryan and J.J. Vallow, two siblings who went missing in September 2019 and were found dead in June 2020.

[9] Much of the city, including BYU-Idaho and the Rexburg Idaho Temple, rests on top of a shield volcano just north of Rigby.

There are lava fields to the west and south of Rexburg, the results of open fissure eruptions from about two thousand years ago.

The nearby Craters of the Moon National Monument presents the most obvious features of this recent activity.

Sediment deposits enriched by volcanism make the surrounding area famous for its production of large starch-rich potatoes.

Rexburg is close to the St. Anthony Sand Dunes, the West Entrance of Yellowstone National Park and the Teton Range.

Rexburg has been referred to as the "reddest place in America,"[17] owing to the area's strong conservative majority and political trends.

Some political experts have considered Rexburg the true antithesis of San Francisco, America's liberal bastion.

[17] Since 1980, no Republican presidential candidate has won less than 57 percent of the Madison County vote.

In that same period, Republican presidential candidates polled more than 90 percent of the county's vote on three occasions: Ronald Reagan in 1984,[18] George W. Bush in 2004[19] and Mitt Romney in 2012.

Rexburg is home to BYU-Idaho, a private institution operated by the LDS Church.

[24] The college offers an eight month program[25] to prepare students to pass the exam to become a licensed massage therapist.

The hospital offers regular classes in an attempt to educate the community on such things as preparing for childbirth and first aid for children,[26] as well as holding Conferences and Health Fairs.
