The discography of the British beat band Herman's Hermits. It contains 18 studio albums, 10 compilation albums, 29 singles and other releases. Their debut single was 1964's "I'm into Something Good", released on MGM Records. The single was an immediate hit, reaching the pop top-15 in the US and the top-10 in Canada. It eventually reached number 1 in the UK after a Columbia Records release there.

The following single, "Show Me Girl", was successful in multiple territories but did not receive a North American release. The group achieved two US number 1 hits with "Mrs. Brown, You've Got a Lovely Daughter" and "I'm Henery the Eighth, I Am". Both singles were international hits, reaching high positions in South Africa, Canada, Australia, and the UK. Several Emi/Columbia EPs were released during this time as well, all having lots of sales. In June 1965, their debut album was released, nearly topping the US charts and peaking at number 16 in the UK. Their second album, Herman's Hermits on Tour achieved similar results in the US, and was certified Gold by the RIAA. Their studio albums continued to make the charts consistently, with their final studio album coming out in late 1968. In 1966, the group collaborated with a number of other artists on When the Boys Meet the Girls, a soundtrack album for the movie starring American singer Connie Francis.

The group continued having a long string of top-40 pop singles, except in the US, when their airplay started drying up, and in 1968 their single "Sunshine Girl" failed to make the Billboard Hot 100, and no other single would break into it. In the UK, however, success continued. "Sunshine Girl" made the top-10, and "My Sentimental Friend" almost topped the charts entirely. The latter was their second number 1 in South Africa. Two compilation albums were released in 1968 and 1969, both seeing less sales compared to the singles. Although 1971's The Most of Herman's Hermits peaked at number 14 in the UK. Many compilations followed it.
