The Queen spent Wednesday night in hospital for preliminary medical checks and is now back at Windsor Castle, Buckingham Palace has said.
The 95-year-old monarch returned from the private hospital in central London at lunchtime on Thursday and is "in good spirits", the palace added.
The Queen had cancelled a visit to Northern Ireland on Wednesday.
She was given medical advice to rest for a few days after a busy schedule of public engagements.
