Sylvia Jung Luke (née Chang, born December 15, 1967) is an American attorney and politician who is serving as the 16th lieutenant governor of Hawaii.

While a junior and senior at Roosevelt High School, Luke conducted independent research at the University of Hawaiʻi at Mānoa on genetics in entomology.

As Judiciary Chair, Luke was instrumental in passing laws to require lifetime registration for the worst sex offenders and all convicted felons to submit DNA samples and hand impressions.

[10] Luke gained a reputation as a powerful lawmaker in her leadership of the House Finance Committee, where she asked tough questions about how state money is spent.

[11] Luke, along with Senator Michelle Kidani and Representative Della Au Belatti, has been instrumental in leading efforts to maximize federal reimbursements for Medicaid.

Luke believes it is important for the Legislature to have transparency and the ability to prioritize spending, including special funds, which are dedicated accounts for specific programs.

She has also tackled other complex fiscal issues, such as addressing temporary hires and introducing legislation for regular reviews of tax credits and exemptions.

Luke's efforts aimed to ensure accountability, effective allocation of public funds, and the Legislature's ability to fulfill its responsibilities.

Using information from the House Select Committee on COVID-19 Economic and Financial Preparedness, which worked with representatives from local and state government, private industry, and nonprofit agencies and organizations to inform the House of Representatives on the State's economic and financial preparedness, funding was allocated for rent subsidies, unemployment insurance, and personal protective equipment (PPE) for schools and hospitals.

In her inauguration speech, Luke described her experiences as a working mother and how important access to preschools and child care is to families who depend on them, citing it as a cost-of-living issue.

[19] In January 2023, Luke launched the Ready Keiki initiative to expand preschool services statewide and build hundreds of classrooms to increase the state's capacity to serve underserved children.

"[33] On August 19, 2023, the South Korean government and Consul General Lee Seo Young worked with Luke to donate $2 million USD for Maui fire disaster relief.
