Little River Band (LRB) are a rock band formed in Melbourne, Australia, in March 1975. The band achieved commercial success in both Australia and the United States. They have sold more than 30 million records; six studio albums reached the top 10 on the Australian Kent Music Report albums chart including Diamantina Cocktail (April 1977) and First Under the Wire (July 1979), which both peaked at No. 2. Nine singles appeared in the top 20 on the related singles chart, with "Help Is on Its Way" (1977) as their only number-one hit. Ten singles reached the top 20 on the Billboard Hot 100 with "Reminiscing" their highest, peaking at No. 3.

Little River Band have received many music awards in Australia. The 1976 line-up of Glenn Shorrock, Graeham Goble, Beeb Birtles, George McArdle, David Briggs and Derek Pellicci were inducted into the Australian Recording Industry Association (ARIA) hall of fame at the 18th annual ARIA Music Awards of 2004. Most of the group's 1970s and 1980s material was written by Goble and/or Shorrock, Birtles and Briggs. In May 2001 the Australasian Performing Right Association (APRA), as part of its 75th anniversary celebrations, named "Cool Change", written by Shorrock, as one of the Top 30 Australian songs of all time. "Reminiscing", written by Goble, received a 5-Million Broadcast Citation from BMI in 2020.

The group have undergone numerous personnel changes, with over 30 members since their formation, including John Farnham as lead singer after Shorrock first departed in 1982. None of the musicians now performing as Little River Band are original members, nor members in the 1970s. In the 1980s, members included Farnham, Wayne Nelson, Stephen Housden, David Hirschfelder and Steve Prestwich. The current line-up is Nelson, Chris Marion, Ryan Ricks, Colin Whinnery and Bruce Wallace – none of whom are Australian. Various legal disputes over the band's name occurred in the 2000s, with Housden filing suit against Birtles, Goble and Shorrock.
