The Prince of Wales was “pleased to be able to welcome Ms Markle to the Royal Family in this way”, the palace added.
Prince Harry’s grandfather, the Duke of Edinburgh, will also attend the wedding, Buckingham Palace confirmed.
Prince Philip, 96, has been recovering from a hip operation.
Ms Markle’s mother, Doria Ragland, will take her daughter to the wedding at St George’s Chapel in Windsor.
