The company says the locations are underperforming or cannot provide its intended customer and employee experience.
Starbucks plans to close 250 stores across North America in its second major round of closures within a year.
Chief Operating Officer Mike Grams told employees that the affected locations either are not producing acceptable financial results or cannot provide the experience Starbucks wants for customers and workers.
The company has not released a complete list of stores or said how many closures will occur in the United States.
Starbucks said it will attempt to transfer affected employees to other locations. Workers who cannot be reassigned will be offered severance support.
Starbucks Workers United said 20 unionized stores are included, representing 8% of the announced closures. The union is requesting additional information and says it intends to bargain over the closures at represented locations.
The company expects approximately $300 million in restructuring charges, including lease-exit costs, separation benefits and noncash expenses related to store assets.
Starbucks closed 627 locations in North America and Europe last September. Despite the latest reductions, the company says it remains committed to expanding its overall North American store count and renovating existing coffeehouses.
