from QPR on a four-year contract.
The France international striker has put pen to
paper on a deal until the summer of 2018, after
Chelsea activated a £10.5million release clause in
the 27-year-old's contract.
Remy joined QPR from Marseille in January 2013,
scoring six goals in 14 games, as Rangers were
relegated from the Premier League.
He then spent the 2013/14 campaign on loan at
Newcastle United, where he scored 14 goals.
Remy, who had also been linked with Arsenal, told
Chelsea's official website: "I feel very happy and
very proud.
"When I heard Chelsea wanted to sign me I said
"let's go" straight away because they are one of the
best clubs in the world.
"I remember the amazing atmosphere at Stamford
Bridge when I played there for Marseille and I can't
wait to play for the first time in front of my new
fans."
Remy came through French side Lyon's youth
academy and made his first-team debut for his
home-town club in 2006, playing for them during
two Ligue 1 title-winning seasons, as well as in the
Champions League.
However, it was at Nice, following a loan spell at
Lens, where the young Remy built his reputation,
earning a move to Marseille in August 2010.
He scored his first Champions League goals during
his opening season for Marseille, playing in two
group games against Chelsea, and was their top
league scorer with 15 goals in 2010/11.
He made his international debut in June 2009,
scoring his first international goal the following
season.
After averaging almost a goal every two games
during two and a half years at Marseille, in January
2013 he moved to QPR and scored on his debut at
West Ham.
After Rangers were relegated, he joined Newcastle
on loan last season, with his goal against Chelsea at
St James' Park in November one of 14 he scored in
the Premier League last season.
He also travelled with the France squad to the
World Cup in Brazil in the summer, making two
substitute appearances.
He played in QPR's first two league games this
season but not in their Capital One Cup defeat by
Burton Albion, so remains eligible to play for
Chelsea in all competitions.
Remy had looked set to join Liverpool earlier
this summer but the proposed switch to Anfield
broke down following a medical.
However, Chelsea boss Jose Mourinho said on
Saturday: "The information we have from specialists
in different areas is he doesn't have a problem to
play football."
