The Labour leader backs a “day of celebration” if the Lionesses claim victory at a sold-out Wembley Stadium on Sunday.
They beat Sweden, the highest-ranked team in the Uefa Women’s Euro 2022 competition, 4-0 in the semi-final on Tuesday.
And on Wednesday night, Germany beat France to set up a mouth-watering final clash.
Speaking about calls for a Bank Holiday, Sir Keir said: “The whole country will be roaring on the Lionesses in the final on Sunday.
“They have already done us proud, but if they win it will be a truly historic achievement – one that should be marked with a proper day of celebration, where clubs can open and promote access for women and girls.”

Sir Keir, before speaking to The Mirror, was in the crowd at Bramall Lane, in Sheffield, with his wife Victoria on Tuesday evening.
Tory former sports minister Tracey Crouch and Lib Dem leader Sir Ed Davey also reportedly backed the idea.
Boris Johnson was under pressure to give workers a bank holiday last summer had England’s men’s team won the Euro 2020 championship.
Speaking before the final against Italy, which ended in penalty heartbreak for the team, Mr Johnson said granting a bank holiday would be “tempting fate”.
After the match on Tuesday he tweeted: “On to Wembley!
“A fantastic result for captain @leahcwilliamson and the @Lionesses tonight against Sweden.
“Come on England, bring it home.”
The Department for Business, Energy and Industrial Strategy (BEIS) has been approached for comment.
