The 2019 State of the Union Address was given by the 45th president of the United States, Donald Trump, on February 5, 2019, at 9:00 p.m. EST, in the chamber of the United States House of Representatives to the 116th United States Congress. It was Trump's second State of the Union Address and his third speech to a joint session of the United States Congress during his first term. Presiding over this joint session was the House speaker, Nancy Pelosi, accompanied by Mike Pence, the vice president, in his capacity as the president of the Senate.

It was the first address to a Democratic-controlled House of Representatives since 2010.

The Democratic Response was given by 2018 Georgia Gubernatorial Nominee Stacey Abrams and the Spanish-language response was given by California Attorney General and former U.S. Representative Xavier Becerra.

The Address was watched by 46.8 million viewers, and aired live on 12 major television networks. Viewership statistics do not include views from online live streams. There were also 15.2 million interactions regarding the Address on social media.

Article II, Section 3, Clause 1 of the United States Constitution states that the president "shall from time to time give to the Congress Information of the State of the Union, and recommend to their Consideration such measures as he shall judge necessary and expedient."

Speaker of the House Nancy Pelosi sent an invitation to President Donald Trump on January 3, 2019, to deliver a "State of the Union address before a Joint Session of Congress on Tuesday, January 29, 2019 in the House Chamber." The invitation was sent just hours after her election to Speaker of the House. On January 6, President Trump commented to reporters that "I will be making the State of the Union on January 29. And I look forward to it. I look forward to it. And I look forward to speaking, really, before the world. We have a lot of great things to say."

The Cabinet of Donald Trump, the heads of the 14 of 15 executive departments, Joint Chiefs of Staff, the nine sitting Supreme Court justices, and members of Congress were invited to attend. Fifteen guests chosen by First Lady Melania Trump were present in the gallery. Energy Secretary Rick Perry was not in attendance as he was named the designated survivor.

Originally scheduled for January 29, House Speaker, Nancy Pelosi, communicated on January 16 that pursuant to the month-long shutdown of the federal government, citing fears of security concerns regarding unpaid Secret Service members, the President could reschedule the Address or submit a written State of the Union to Congress. Pelosi formally communicated on January 23 that a resolution authorizing the speech in the House chamber would not be considered until the shutdown had ended. Trump, who had earlier mulled giving the speech in an alternative location, announced he would wait to give the State of the Union Address after the end of the shutdown. The shutdown was suspended on January 25, and on January 28, Pelosi issued an invitation for Trump to deliver the Address in the Capitol Building on February 5, 2019. On the same day, Trump accepted Pelosi's proposed date.
