"Worst That Could Happen" is a song with lyrics and music written by singer-songwriter Jimmy Webb.

Originally recorded by the 5th Dimension on their 1967 album of nearly all-Jimmy Webb songs, The Magic Garden, "Worst That Could Happen" was later recorded by the Brooklyn Bridge and reached the Billboard Hot 100's top 40, at #38 on January 4, 1969, peaking at #3 on February 1-8, 1969.

It has been stated that, along with "MacArthur Park" and "By the Time I Get to Phoenix", "Worst That Could Happen" is about a relationship that Webb had with a woman named Susan.
