ELV1S: 30 #1 Hits is a greatest hits collection of songs by American rock and roll icon Elvis Presley that reached No. 1 in both the United States, Australian and the United Kingdom's album charts. The album was released by RCA Records on September 24, 2002. It is the first Elvis Presley album to feature the remix of "A Little Less Conversation" by Junkie XL that was released earlier in the year (see 2002 in music) and reached No. 1 in the UK. This style of compilation, dovetailing number one hits from the two largest record markets in the world, was inspired by the Beatles' 1, which had become a worldwide hit in 2000. Conversely, the latter album had been somewhat inspired by Presley's "The Number Ones hits", released thirteen years earlier, in 1987, and which had earned an RIAA Platinum X3 certification, for selling over 3 million copies, by July 19, 1999. "The Number one hits" was, in fact, in both its RCA denominations (RCA LP 6382-1-R, and RCA CD, 6382-2-R), the first compilation of number one hits by any single artist or band in any country in the world.

When released, ELV1S: 30 #1 Hits was an instant success, going straight to the top of the albums charts in several countries and shipping mass quantities around the world. By 2003 the album had received certifications in more than fifteen regions and had sold millions of copies worldwide. A companion album, 2nd to None, was released the next year.
