The United States fifty-dollar bill ($50) is a denomination of United States currency. The 18th U.S. President (1869-77), Ulysses S. Grant, is featured on the obverse, while the U.S. Capitol is featured on the reverse. All current-issue $50 bills are Federal Reserve Notes.

As of December 2013, the average life of a $50 bill in circulation is 8.5 years, or approximately 102 months, before it is replaced due to wear. Approximately 6% of all notes printed in 2009 were $50 bills They are delivered by Federal Reserve Banks in brown straps.

In 2005, a proposal to put Ronald Reagan's portrait on the $50 bill was put forward, but never went beyond the House Financial Services Committee, even though Republicans controlled the House. In 2010, North Carolina Republican Patrick McHenry introduced another bill to put Reagan's portrait on the $50 bill.
