Germany participated in the Eurovision Song Contest 2017 with the song Perfect Life, performed by Levina and written by Lindsey Ray, Lindy Robbins and Dave Bassett. The German entry was selected through the national final Unser Song 2017, organised by the German broadcaster ARD in collaboration with Norddeutscher Rundfunk (NDR).

Prior to the 2017 Contest, Germany had participated in the Eurovision Song Contest sixty times since its debut as one of seven countries to take part in 1956. Germany has won the contest on two occasions: in 1982 with the song "Ein bißchen Frieden" performed by Nicole and in 2010 with the song "Satellite" performed by Lena. Germany, to this point, has been noted for having competed in the contest more than any other country; they have competed in every contest since the first edition in 1956 except for the 1996 contest when the nation was eliminated in a pre-contest elimination round. In 2016, the German entry "Ghost" performed by Jamie-Lee placed last out of twenty-six competing songs with eleven points; it was the second year in a row Germany placed last in the final.

The German national broadcaster, ARD, broadcasts the event within Germany and delegates the selection of the nation's entry to the regional broadcaster Norddeutscher Rundfunk (NDR). NDR confirmed that Germany would participate in the 2017 Eurovision Song Contest on 23 May 2016. Since 2013, multi-artist national finals had determined both the songs and performers to compete at Eurovision for Germany. For their 2017 entry, the broadcaster announced on 14 September 2016 that they would revert back to a casting show format for the national final, similar to the format used in 2010 and 2012, which resulted in a first place and a top ten result respectively at Eurovision for Germany.
