一张Lolcat（英语发音：/ˈlɒlkæt/ LOL-kat）是指在一幅家猫的照片上加上了字幕的图片。图中的字幕通常会以特异的方式串出，或是以不合符文法和幽默的方式书写，而以此方式编写的句字称之为「lolspeak」（LOL语）或「 kitty pidgin」（小猫皮钦语）。

「Lolcat」一词是由英语「laughing out loud」（大声笑）的缩写「LOL」和「cat」（猫）二词合成而成。Lolcat图片一般都是为分享至贴图讨论版或其他网络讨论区而创作。

A lolcat (pronounced /ˈlɒlkæt/ LOL-kat) is an image macro of one or more cats. The image's text is often idiosyncratic and grammatically incorrect. Its use in this way is known as "lolspeak" or "kitty pidgin".

"Lolcat" is a compound word of the acronymic abbreviation for "laugh out loud" (LOL) and the word "cat". A synonym for "lolcat" is cat macro, since the images are a type of image macro. Lolcats are commonly designed for photo sharing imageboards and other Internet forums.
