Here are seven things to know about the royal mom-to-be.
Her full maiden name was Rachel Meghan Markle. She grew up in the Los Angeles area, where she attended Catholic school.
Her father, Thomas Markle, was a Hollywood lighting director, and her mother, Doria Ragland, a yoga instructor and psychotherapist. Her parents split when she was young.
Her parents released a joint statement after her engagement announcement, saying:
"We are incredibly happy for Meghan and Harry. Our daughter has always been a kind and loving person. To see her union with Harry, who shares the same qualities, is a source of great joy for us as parents. We wish them a lifetime of happiness and are very excited for their future together."
Markle, who is biracial, penned an essay about her experiences for Elle Magazine in 2015, writing, "'What are you?' A question I get asked every week of my life, often every day."
She attended Northwestern University, where she graduated from the School of Communication in 2003. Markle was also a member of the Kappa Kappa Gamma sorority.
Markle returned to Northwestern for a visit in 2014, when she reminisced, "The 24-hour Burger King also definitely helped me put on the Freshman Fifteen."
The duchess was known as a trendsetter even before she was a duchess. And it's a good thing, too, because as a member of the royal family everything she wears has the potential to make headlines.

Outside her career and relationship, Markle is also known for her humanitarian work and for her activism.
In March of 2017, she wrote an essay called "How Periods Affect Potential," based on her time as a World Vision ambassador in India.
When it comes to women's rights, Markle is not afraid to speak out.
"It's not just a women's fight for women. It's a people's fight for people," she told Larry King in 2016.
