The Royal Challengers Bangalore (often abbreviated as RCB) are a franchise cricket team based in Bangalore, Karnataka, that plays in the Indian Premier League (IPL). It was founded in 2008 by United Spirits and named after the company's liquor brand Royal Challenge. Since its inception, the team has played its home matches at the M. Chinnaswamy Stadium.

The Royal Challengers have never won the IPL but finished runners-up on three occasions between 2009 and 2016. Their lack of success over the years despite the presence of various notable players has earned them the tag of "underachievers". The team holds the records of both the highest and the lowest totals in the IPL – 263/5 and 49 respectively.

In September 2007, the Board of Control for Cricket in India (BCCI) announced the establishment of the Indian Premier League, a Twenty20 competition to be started in 2008. The teams for the competition, representing 8 different cities of India, including Bangalore, were put up on auction in Mumbai on 20 February 2008. The Bangalore franchise was purchased by Vijay Mallya, who paid US$111.6 million for it. This was the second highest bid for a team, next only to Reliance Industries' bid of US$111.9 million for the Mumbai Indians.

The brand value of Royal Challengers Bangalore was estimated to be ₹595 crore (US$83 million) in 2019, according to a survey conducted by Duff & Phelps.

The logo initially consisted the RC emblem in yellow on a circular red base with the black text "Royal Challengers Bangalore" in standard format surrounding the circular logo. The RC crown emblem with the roaring lion placed on the top of the logo was derived from the original Royal Challenge logo. No significant changes took place in the design of the logo except for the replacement of colour yellow with gold from 2009. This logo also had a dotted white circle around the RC emblem. The team also uses an alternate logo for the Game for Green matches where the green plants surround the logo and the text Game for Green is placed below the logo. The logo was redesigned in 2016 with the inclusion of black as a secondary color. The lion emblem in the crest was enlarged and the shield was omitted in the new design. In 2020, a new logo was unveiled featuring a bigger lion and the crown returning from the previous logo. The RC emblem was omitted for this crest
