Holly Katherine Allen was the runner-up of Big Brother 21 (US).

Holly is known for her showmance with Jackson Michie and her preexisting relationship with Kathryn Dunn. As an early member of Gr8ful, Holly remained under the radar until the bigger targets went out. On Day 44 her prior relationship with Kathryn was outed by Jack Matthews, which caused her and Jackson to defect from their alliance. Holly and Jackson's success in competitions and relationship with Cliff Hogg III and Nicole Anthony kept her safe, until the final 5, where she was nominated by default. Jackson saved her from eviction by falsely framing Tommy Bracco of targeting Cliff and Nicole. After Jackson won the final Head of Household, he chose to take Holly to the final two. Unfortunately for Holly, her subtle game wasn't preferred over Jackson's aggressive game-play, causing her to finish in second place with 3 votes to win.
