Love Is... is a comic strip created by New Zealand cartoonist Kim Casali (née Grove) in the 1960s. The cartoons originated from a series of love notes that Grove drew for her future husband, Roberto Casali. They were published in booklets in the late 1960s before appearing in strip form in a newspaper in 1970, under the pen name "Kim". They were syndicated soon after and the strip is syndicated worldwide today by Tribune Content Agency. One of her most famous drawings, "Love Is...being able to say you are sorry", published on February 9, 1972, was marketed internationally for many years in print, on cards and on souvenirs. The beginning of the strip coincided closely with the 1970 film Love Story. The film's signature line is "Love means never having to say you're sorry." At the height of their popularity in the 1970s the cartoons were earning Casali £4-5 million annually.

Roberto Casali was diagnosed with terminal cancer in 1975 and Kim stopped working on the cartoon to spend more time with him. Casali commissioned London-based British cartoonist Bill Asprey to take over the writing and drawing of the daily cartoons for her, under her pen name. Asprey has produced the cartoon continuously since 1975. Upon her death in 1997, Casali's son Stefano took over Minikim, the company which handles the intellectual rights.

The strip appears daily except Sunday.
