Oprah’s campaigning in 2020 — for Weight Watchers.

America’s most beloved talk show host, and likely our most visible yo-yo dieter, is hitting the road for “WW Reimagined” (yes, it no longer goes by its full, former moniker) in 2020.

The “Oprah’s 2020 Vision: Your Life in Focus” tour will hit nine cities starting in January. The former host and chairwoman of Harpo Productions is promising a lineup of wellness experts and celebrity guests for her self-help stadium tour.

“I’ve had my share of life’s ups and downs,” the Mississippi native, who owns six homes, and spends the bulk of her time in her mansion in Montecito, Calif., says in a promo for the tour. “We’ll come together (with some of my friends) to support each other for a stronger, healthier and more abundant life.”

Tickets to the Oprah tour will go on sale on Sept. 13, with a presale option for American Express cardholders, VIPs and WW members starting Sept. 9 on Ticketmaster.com. Tour dates span from January to March, including Brooklyn’s Barclays Center on Feb. 8.

Oprah’s last motivational speaking run, “Oprah’s The Life You Want Weekend,” was in 2014, and featured New Age guru Deepak Chopra, spiritualist Mark Nepo and “Eat, Pray, Love” author Elizabeth Gilbert.

One million dollars of the proceeds from the tour will go to the WW Good charity, which feeds underserved communities. Expect “movement experiences” and a “specially created WW box lunch” at the event, per Oprah’s website.

Winfrey has been the star spokesperson for WW, a points-based weight loss system, since 2015 and owns about 8 percent of the company.

Still, some Oprah fans were disappointed after speculation last year that she might be gunning for the White House. Social-media star Parker Kit Hill wrote on Instagram, “Ugh I thought this was you saying you’re about to run for president.”
