Mianxin (綿忻; 9 March 1805 – 27 September 1828) was Qing dynasty imperial prince as the fourth son of the Jiaqing Emperor. Mianxin was made the first holder of the Prince Rui of the First Rank title in 1819. In contrary to existing iron-cap Prince Rui of the First Rank peerage, the first character in the title was translated into Manchu as "sabingga". The peerage was not extinct as Mianxin had a legitimate male heir and the peerage was not granted perpetual inheritability, which meant that his successors would hold diminished ranks.
