The opener scored 208 runs from 331 balls in the first innings at Trent Bridge, surpassing Betty Snowball's knock of 189 against New Zealand in February 1935
Records tumbled on day three of the Women's Ashes Test at Trent Bridge as Tammy Beaumont became the first English woman to score a double century in a Test match.
Beaumont scored 208 runs off 331 balls at the top of the order, batting for 498 minutes before finally being bowled by Ashleigh Gardner.
With her exit, England were all out for 463, trailing Australia by 10 runs.
In the process, Beaumont broke the record for the highest Test score by an English woman, which had stood for 88 years.

In February 1935, Betty Snowball scored 189 runs in the first innings of a standalone Test against New Zealand in Christchurch. England went on to declare on 503 for 5 and won the match by an innings and 337 runs.
According to Cricket Archive, Beaumont's knock is the fifth highest individual score in the history of women's Test cricket and the highest individual knock against Australia, surpassing Rachael Heyhoe Flint's 179 in July 1976.
Taking 317 balls to reach 200, it is the second fastest double hundred in terms of balls faced behind Australia's Karen Rolton, who required 306 balls to reach the milestone against England in 2001.
Earlier in the Test, Beaumont had become just the second English woman to score a century in all three formats of international cricket, following in the footsteps of captain Heather Knight.
Her previous high score (70) came back in November 2017, against Australia in Sydney.
