"Here Today" is a song written by Brian Wilson and Tony Asher for American rock band The Beach Boys, released on their 1966 album Pet Sounds. It is the tenth track on the album. The song's lyric is expressed from the perspective of a narrator who warns the listener of the inevitable heartbreak that will result from his newfound love. It was later included as the B-side to the 1967 single "Darlin'".

Stephen Davis, who reviewed Pet Sounds, stated that "Here Today" "portrays a pessimism and disaffection that jars with the previous optimism. It is the end of the affair..." Donald Guarisco of Allmusic described the song as "a highlight of Pet Sounds" and "one of Brian Wilson's most ambitious arrangements."

The song was composed and produced by Brian Wilson with the lyrics by Tony Asher about love being "here today and it's gone tomorrow," with the potential for heartbreak that never lies too far away "a brand new love affair is such a beautiful thing/but if you're not careful, think about the pain it can bring."Tony Asher has said, "That's a song that has a number of little sections to it that are quite different. It was not one of the easier songs to write on the album. It was, as I recall, a song that I wrote quite a lot to, much of which we didn't use. It was sort of a struggle before we got a lyric that Brian was happy with." He added in 1996, "'Here Today' was probably one of the mystery songs on the album. I don't really know what it's about. I liked it, but yet I didn't. I don't really identify with that song like I do with 'You Still Believe In Me', or 'Caroline, No.' It was just one of those songs in there, one little song."

In 1990, Wilson said: "'Here Today' was a work of art in my opinion. It was assertive track with utilization of basses played up higher. The trombones gave it that masculine touch.." Musicologist Walter Everett notes of the song: "One of the most remarkable parts in the bass literature occurs in 1:47–2:02 ... where rapidly repeated bass notes are all sevenths, 1 appearing beneath ii, in alternation with ♭7 placed below I."
