Sara G. Innamorato is an American politician serving as the county executive of Allegheny County, Pennsylvania since 2024. She was a member of the Pennsylvania House of Representatives for the 21st district from 2019 to 2023.

Innamorato was raised in Ross Township and attended the North Hills School District. She graduated magna cum laude from the University of Pittsburgh with a Bachelor of Science in business.

After the 2008 economic crash, she secured a spot in a leadership program at Apple. She then left the private sector to work in the nonprofit sector, focusing on issues of vacant land reclamation, food justice, and digital equity. She started Innamo Co., an independent marketing firm focused on "social good". Innamorato is a co-founder of She Runs SWPA, a non-partisan organization focused on encouraging women to run for office.

Then a member of the Democratic Socialists of America (DSA), she won the Democratic Party nomination for the seat by defeating incumbent Dom Costa in the 2018 primary election with over 64% of the vote.

Although Innamorato was unopposed on the ballot, Costa launched a write-in campaign late in the election cycle. Costa went public with the bid following a podcast interview in which Innamorato was quoted saying, "My district, which I know is like white working class, poor folk, who are racist, because it's so much easier for them to look to their side and say, 'I'm going to blame that person.'" Costa campaign head Gary Britcher argued that Innamorato had called the district "racist".

Innamorato responded in an interview, stating that the comment had been taken out of context: "'From the beginning of this campaign, I've talked about my experience growing up in that district, and about the kindness of neighborhood (sic) who helped me through the instability of growing up.' Her point, she said, was that white working class voters 'are being exploited from all sides,' by economic and political elites who play on racial tensions to distract them from issues of economic injustice. 'Racism exists everywhere,' she said. 'My job is to represent everyone, and to not shy away from tough conversations.'"

Innamorato won the general election with 19,985 votes (85%), with Costa and other write-in candidates receiving 3,584 votes (15%). After the election, allegations surfaced that two violations of Pennsylvania campaign finance law were committed by the PAC "Americans Against Socialism," the principal funding mechanism for the marketing firm employed by the Costa write-in campaign.

Innamorato's affiliation with the Democratic Socialists of America ended in 2019.
