Facebook chief Mark Zuckerberg is to give evidence to a US committee on April 11, according to officials.
Representatives Greg Walden and Frank Pallone said the hearing of the oversight committee will focus on Facebook's "use and protection of user data".
Facebook is facing scrutiny over its data collection following allegations that political consulting firm Cambridge Analytica obtained data on tens of millions of Facebook users to try to influence elections.
Mr Walden is the House Energy and Commerce Committee chairman, and Mr Pallone is the panel's top ranking Democrat.
They say the hearing will be "an important opportunity to shed light on critical consumer data privacy issues and help all Americans better understand what happens to their personal information online".
The committee is the first of three congressional panels that requested Mr Zuckerberg's evidence to announce a hearing date. The Senate Commerce and Judiciary committees also have called for him to appear.
Mr Zuckerberg said during a March 21 interview on CNN that he would be "happy" to give evidence before Congress, but only if he was the right person to do that.
He said there might be other Facebook officials better positioned to appear, depending on what Congress wanted to know.
Mr Walden and Mr Pallone said a day later that as Facebook's top executive, Mr Zuckerberg was the "right witness to provide answers to the American people".
