List of new members of the 112th United States Congress

The 112th United States Congress began on January 3, 2011. There were 13 new senators (one Democrat, 12 Republicans) and 94 new representatives (nine Democrats, 85 Republicans) at the start of its first session. Additionally, three senators (one Democrat, two Republicans) and 10 representatives (seven Democrats, three Republicans) took office on various dates in order to fill vacancies during the 112th Congress before it ended on January 3, 2013.

The president of the House Democratic freshman class was Terri Sewell of Alabama, while the president of the House Republican freshman class was Austin Scott of Georgia. Additionally, the Republican's freshmen liaisons were Kristi Noem of South Dakota and Tim Scott of South Carolina.

This freshmen class was overwhelmingly Republican, resulting in an even larger prevalence of Republican freshmen than during the Republican Revolution of 1994, with approximately 23% of the 47 elected Republican senators and 33% of the 242 elected Republican representatives being first-timers.
