The title Baron Grey of Powis (1482–1552) was created for the great-grandson of Joan Charleton (c.1400–1425), co-heiress and 6th Lady of Powis (Powys) and her husband, Sir John Grey, 1st Earl of Tankerville (1384–1421) after the death of Joan's father, Edward Charleton, 5th Baron Cherleton left the title in abeyance.

After several generations of Lords Grey of Powis, Joan and John's great-grandson, John Grey, obtained the title "Baron Grey" by Barony Writ of Summons on 15 November 1482. The title passed into abeyance with the death of John Grey, 1st Baron Grey of Powis' grandson, Edward Grey. Edward Grey, illegitimate son of Edward Grey, the last Baron Grey of Powis (died 1551), sold Powis to Sir Edward Herbert, son of William Herbert, 1st Earl of Pembroke (1501–1570).
