The short answer

Wyoming has consistently ranked highest in recent years, with an age-adjusted rate of roughly 30 per 100,000 people — more than double the national rate of about 14 per 100,000. It's part of a cluster sometimes called the "suicide belt": Montana, Alaska, New Mexico, Idaho, Colorado, South Dakota, and Nevada all rank near the top, while the lowest rates are in the Northeast (New Jersey, New York, Massachusetts) and Washington, D.C.

One caveat: Wyoming has under 600,000 residents, so its rate swings noticeably year to year, and exact rankings among the top few states shuffle depending on the data year.

Factors researchers point to

Firearm access. This is the single most emphasized factor. Suicide attempts with a gun are fatal roughly 85–90% of the time versus a few percent for most other methods, so ready access converts impulsive crises into deaths. Wyoming has among the highest household gun ownership rates in the country, and firearms account for about 70% of its suicides versus roughly 55% nationally. Studies consistently find state gun ownership rates correlate with suicide rates even after controlling for rates of attempted suicide and depression.

Rurality and isolation. Low population density, long distances, harsh winters, and thin social infrastructure all correlate with higher rates.

Mental health care access. Frontier states have severe provider shortages, few inpatient psychiatric beds, and long travel times. Emergency medical response times are also longer, which reduces survival after an attempt.

Demographics. The highest-risk group nationally is middle-aged and older white men, who make up a large share of these states' populations. Separately, American Indian and Alaska Native communities have the highest rates of any racial/ethnic group in the U.S., which weighs heavily in Alaska, Montana, New Mexico, and the Dakotas — tied to the legacy of colonization, forced removal, and concentrated poverty.

Occupation and economics. Extractive industries (mining, oil and gas), agriculture, and construction have elevated suicide rates, and boom-bust cycles create financial instability. These states also have high veteran populations per capita.

Alcohol use. The Mountain West has high binge-drinking rates, and alcohol is a major acute risk factor.

Culture. Norms of stoicism and self-reliance are thought to discourage help-seeking, though this is harder to measure.

Altitude — a contested hypothesis. Several studies (Brenner and colleagues, among others) found that mean county elevation predicts suicide rates even after adjusting for gun ownership, rurality, income, and population density. The proposed mechanism is that chronic mild hypoxia at altitude impairs serotonin synthesis and brain bioenergetics, worsening mood disorders. Interestingly, altitude correlates with lower all-cause mortality, making suicide an outlier. This remains debated, and skeptics argue it's residual confounding with the region's other characteristics.

Most researchers see these as compounding rather than competing explanations: a high-risk population, under economic stress, with limited care, in an environment where lethal means are close at hand.
