Bafta Best Supporting Actress: Winners And Nominees You Should Know
BAFTA Best Supporting Actress winners and nominees
The latest BAFTA best supporting actress winner is Wunmi Mosaku for Sinners at the 2026 BAFTA Film Awards, where she triumphed over nominees including Odessa A'zion, Inga Ibsdotter Lilleaas, Carey Mulligan, Teyana Taylor, and Emily Watson.
BAFTA's supporting-actress category recognizes outstanding film performances in a supporting role, and the award has been presented annually since 1968, with the ceremony typically honoring films released the previous year.
2026 nominees and winner
The 2026 race was especially strong because the field combined established stars and rising performers, with BAFTA voters ultimately choosing Mosaku's work in Sinners as the winner.
| Year | Winner | Film | Other nominees |
|---|---|---|---|
| 2026 | Wunmi Mosaku | Sinners | Odessa A'zion, Inga Ibsdotter Lilleaas, Carey Mulligan, Teyana Taylor, Emily Watson |
How the category works
BAFTA's supporting actress category is intended to honor the performer who delivered the most impressive supporting female performance in a film, rather than the film's lead.
That distinction matters because supporting roles often shape tone, conflict, or emotional balance without carrying the full narrative burden, which is why the category regularly highlights scene-stealing performances.
Notable recent context
The 2026 ceremony was dominated by One Battle After Another and Sinners across the wider awards slate, but the supporting-actress prize still went to Mosaku, reinforcing how BAFTA often spreads recognition across multiple films.
"Winner: Wunmi Mosaku - Sinners"
Across the broader 2026 BAFTA Film Awards, One Battle After Another led nominations with 14 and Sinners followed with 13, a useful marker of the competitive environment around the supporting-actress field.

- It has been part of the BAFTA Film Awards since 1968.
- It focuses on supporting work, not lead billing.
- It often includes both major stars and breakout performers.
- The winner is selected by BAFTA voters from a shortlist of nominees.

Why 2026 mattered
