The 2016 United States Senate election in Hawaii was held November 8, 2016, concurrently with the 2016 U.S. presidential election as well as other elections to the United States Senate and House of Representatives and various state and local elections. The primaries were held August 13. Incumbent Democratic U.S. Senator Brian Schatz won reelection to his first full term in office, defeating Republican former state legislator John Carroll.

Background In 2011, Daniel Inouye announced that he planned to run for a record tenth term in 2016, when he would have been 92 years old. He also said, "I have told my staff and I have told my family that when the time comes, when you question my sanity or question my ability to do things physically or mentally, I don't want you to hesitate, do everything to get me out of here, because I want to make certain the people of Hawaii get the best representation possible."

Inouye died on December 17, 2012. Hawaii Governor Neil Abercrombie appointed Lieutenant Governor Brian Schatz, a Democrat, to succeed Inouye. Schatz won a 2014 special election to serve the remainder of Inouye's term.
