I'll look up the current U.S. Representative for Illinois's 14th congressional district for you. Your U.S. Representative for Illinois's 14th congressional district (IL-14) is **Lauren Underwood** (Democrat). Lauren Underwood, D-Naperville, retained her seat in the Illinois 14th Congressional district. She is a Democrat from Naperville who defeated incumbent Randy Hultgren to win the seat , having first taken office in 2019. If you'd like, I can also help you find her office contact information or details about the district. Note that district boundaries and representatives can change with redistricting and elections, so it's always worth confirming with the official [House.gov](https://www.house.gov) directory for the most up-to-date information.
