These pictures were taken by her mother the Duchess of Cambridge, in early November at their family home, Anmer Hall in Norfolk.
Princess Charlotte, who is fourth in line for the British throne, was born on May 2 this year.
The duchess took a joint portrait of her two children - George, aged two, and Charlotte - a few weeks after her daughter was born in May.
The first official photographs of Princess Charlotte were released by the British Royal family in July. The last time the princess was seen in public was in July during her christening.
"The duke and duchess continue to receive warm messages about Princess Charlotte from all around the world and they hope that everyone enjoys these lovely photos as much as they do," said a statement issued by the palace.
