The Twenty Ninth Hawaii State Legislature, consisting of the Hawaii House of Representatives and the Hawaii Senate, was constituted in the U.S. state of Hawaii from November 10, 2016, to November 6, 2018, during the final two years of David Ige's first term as governor.

The 2016 elections gave the Democrats an even larger majority in both legislative bodies, with the losses of one Republican representative and lone Republican senator Sam Slom.

On March 22, 2017, former House Minority Leader Beth Fukumoto announced she would leave the Republican Party and seek membership in the Democratic Party.
