The stadium was named the City of Manchester Stadium by Manchester City Council before construction began in December 1999, but has a number of commonly used alternatives.
City of Manchester Stadium is abbreviated to CoMS when written and spoken.
Eastlands refers to the site and the stadium before they were named SportCity and CoMS respectively, and remains in common usage for both the stadium and the whole complex, as does SportCity but with less frequency.
The stadium was also officially referred to as Manchester City Stadium for the 2015 Rugby World Cup.
The football club, under its new ownership, renegotiated its 250-year lease with the city council in October 2010, gaining the naming rights in return for a substantial increase in rent.
The stadium was renamed the Etihad Stadium by the club in July 2011 as part of a ten-year agreement with the team kit sponsors Etihad Airways.
The agreement encompasses sponsorship of the stadium's name, extends the team kit sponsorship for ten years, and relocated the club's youth academy and training facilities to the City Football Academy onto the Etihad Campus development across the road from the stadium.

Despite being a continuous oval bowl, each side of the stadium is named in the manner of a traditional football ground.
All sides were initially named by compass direction (North Stand and South Stand for the ends, East Stand and West Stand for the sides).
In February 2004, after a vote by fans, the West Stand was renamed the Colin Bell Stand in honour of the former player.
The vote was almost cancelled (and the stand instead named after Joe Mercer) due to suspicions it had been hijacked by rival fans who wished to dub the renamed stand The Bell End.
However, core supporters of the club made it clear they still wished the stand named after their hero.
The East Stand is unofficially known by fans as the Kippax as a tribute to the very vocal east stand at the club's Maine Road ground.

The North Stand is the only part of the stadium built after the Commonwealth Games, during the stadium's conversion.
The temporary unroofed north stand it replaced had been dubbed the New Gene Kelly Stand by supporters, a reference to the unroofed corner between the Kippax and the North Stand at the club's former Maine Road home, because, being exposed to the elements, they frequently found themselves "singing in the rain".
Commencing season 2010–11, seating in the North Stand has been restricted to only supporters accompanied by children, resulting in this end of the ground now being commonly referred to as the Family Stand.
 Although the North Stand has never been officially renamed and is still frequently referenced that way, most external ticketing offices and stadium guides, in addition to the club itself, now preferentially label and refer to this section of the ground as the Family Stand when discussing seating and ticket sales.
Supporters initially dubbed the South Stand the Scoreboard End (the former name of the North Stand at Maine Road), and it houses the majority of City's more vocal fans.
Supporters of visiting teams are also normally allocated seats in this stand, as it has ready access from the visitor supporter coach park.
From 2003 to 2006, the South Stand was renamed the Key 103 Stand for sponsorship reasons, though this was largely ignored by regular patrons.
The November 2018 consultation exercise on further expansion options envisages the North Stand then becoming the Home End, with no corporate hospitality areas, a greatly extended second tier, "affordable" ticket prices and possible areas capable of conversion to safe standing.
The singing area would then be in the North Stand, and the Family Stand would be relocated elsewhere in the Stadium.
