The singer will perform three headline sets at the Atlantic City Revel Casino between May 25-27 in honour of the $2.4bn resort's grand opening.
The shows will be Beyoncé's first since giving birth to her daughter Blue Ivy back in January.
Speaking in a behind-the-scenes video about the gigs, the star confessed: "It is exciting. I feel a little nervous.
"I'm enjoying being a mother so it's like going back to my old job. It is a little strange, but it's important that you don't lose yourself, still have your own passions. I'm back to work, I'm back to business."
Earlier this month it was reported that Beyoncé was training five times a week to get back in shape after her pregnancy.
