Jerjer (哲哲; translated as "lady"/"beauty"; 31 May 1599 – 28 May 1649), of the Khorchin Mongol Borjigit clan, was the consort of Hong Taiji.

Jerjer was born on the eighth day of the intercalary fourth lunar month in the 27th year of the reign of the Wanli Emperor, which translates to 31 May 1599 in the Gregorian calendar.

Lady Borjigit's niece, Bumbutai, the future Empress Dowager Zhaosheng, would marry Hong Taiji in March or April 1625.

Another niece, Harjol, the future primary consort Minhui, would marry Hong Taiji on 6 December 1634.

When Hong Taiji conferred titles on his five primary spouses in August 1636, he instated Jerjer as his empress.
