Home support is certainly strong for who is hoping to take home the Best Actress Award at Sunday night's ceremony.
The Irish actress, 36, has had an incredible awards season, scooping up the Best Actress gong at the , , a Screen Actors Guild and Critics' Choice Award for her role in Hamnet.
And fans from her hometown of Killarney showed their support on Sunday as they put up signs and banners in support of the star ahead of the prestigious night.
One banner read 'Oscar is on the way' beside Jessie's face and an Oscar trophy.
Another outside of a pub showed Jessie dressed in all green as it advertised St Patrick's festival in the town.
Elsewhere a talented artist appeared to have created a mural of Jessie's face in black and white on a pink background.

It comes after Jessie shared her nerves ahead of the Oscars as she reflected on her 'insane' experience with Timothée Chalamet and Emma Stone at the Oscars luncheon when they all posed for a 'class photo' together.
The down to earth mother-of-one says winning an Oscar is 'beyond her wildest expectations' and joked 'she'll be 80 before she takes it all in'.
Speaking in an interview ahead of her glamorous appearance at the Dolby Theatre, she said: 'It's kind of hard to take in. I think probably when I'm 80, I'll have a really good answer.
'Going to the Oscar nominee luncheon and, being completely honest, sometimes you're getting in the car and you're like, "Oh god, I'm tired. And I have a six-month-old, and I should be at home changing her nappy. What am I doing? And I don't know anybody there, I'm scared"'.
Reflecting on her 'insane and cute' class photograph with fellow nominees and starry guests, she told The Mirror: 'I was watching everybody get up and you've got, like Guillermo del Toro and Rose Byrne, Timothée Chalamet, Emma Stone and I'm ike, "God, I cannot take this for granted, this moment".
'It's something I never, ever expected. I thought I would be lucky enough to peep behind the curtain and be in a play. This is beyond my wildest expectations.'
It was announced in January that Jessie has earned an Oscar nomination for Best Actress in a Leading Role for Hamnet.
Actress in a Leading Role will be a highly competitive field as Jessie goes up against Rose Byrne - If I Had Legs I'd Kick You, Kate Hudson - Song Sung Blue, Renate Reinsve - Sentimental Value and Emma Stone - Bugonia.

Jessie said she is 'so proud and honoured' to have been nominated for her portrayal of Agatha Shakespeare.
Speaking with The Hollywood Reporter, she said: 'My baby's screaming in the background, but I am thrilled. I'm so proud and honoured to be beside all those extraordinary women and to be there with Hamnet. I'm delighted.'
Hamnet is nominated for a total of eight awards, including the coveted Best Picture accolade and Best Director for Chloe Zhao, but Paul Mescal was a surprise snub in the Best Supporting Actor category.
The film - about the death of William Shakespeare and Agnes Shakespeare's son Hamnet - has received wide critical acclaim following its release in January.
It has picked up top gongs during the awards season so far, and looks set to be a big winner at the Oscars.
