Grant William McLennan (12 February 1958 – 6 May 2006) was an Australian singer-songwriter with the alternative rock band The Go-Betweens, which he co-founded with Robert Forster in Brisbane, Australia in 1977. In a career spanning almost thirty years, his work with The Go-Betweens (1977–89, and resuming 2000–06) is complemented by several solo releases and side-project collaborations with other performers. McLennan received a number of accolades recognising his achievements and contributions as songwriter and lyricist, including the naming of his 1983 composition "Cattle and Cane" by the Australasian Performing Right Association (APRA) as one of the 30 greatest Australian songs of all time.

McLennan died suddenly of a heart attack at the age of 48.
