The locations are at 9th and Market Streets in The Gallery in Center City Philadelphia and on the 900 block of Orthodox Street in Juniata Park.
The company says both stores will start liquidation sales on February 9th and close permanently in late April.
A Kmart spokesman told Action News Thursday that the closures "are part of a series of actions we're taking to reduce on-going expenses, adjust our asset base, and accelerate the transformation of our business model. These actions will better enable us to focus our investments on serving our customers and members through integrated retail at the store, online and in the home."
Kmart says 289 employees will be affected. Some will be eligible for severance and invited to apply for jobs at other Kmart or Sears stores.
The 9th and Market Street store currently employees 120 people, while the store on Orthodox Street has 169 employees. Most work part time or hourly.
