Katie caught up with Archdeacon Treweek to see what she was most excited about in her new job.
The new Bishop of Gloucester has reacted to her appointment, and recorded a video - posted to the Diocese of Gloucester website.
The first female diocesan bishop has been appointed by the Church of England.
The new Bishop of Gloucester will be Rachel Treweek, who is currently the Archdeacon of Hackney in the London Diocese.
She takes on the role after The Right Reverend Michael Perham retired in November.
Archdeacon Treweek becomes the third female bishop. The 52-year-old has been given a more senior position than the junior, or suffragan, posts two women have so far been given. Her role means she is the first female bishop to sit in the House of Lords.
After the announcement Archdeacon Treweek said:
The Church of England's first woman bishop is the Rt Rev Libby Lane, who was consecrated as the eighth Bishop of Stockport at York Minster in January.
