It has several names. The most common is probably hash. In North American English, it’s sometimes called the pound sign and used as a symbol for pounds weight: this can be confusing for British people for whom a pound sign is £. It’s also known as the number sign in North American English, in contexts such as go to question #2 . In a musical context, the symbol is known as a sharp. The picturesque name octothorpe has also been introduced: it’s said to have been invented by an employee of Bell Laboratories in the 1960s, in honour of the American athlete Jim Thorpe (with the octo- part deriving from the symbol’s eight points). In the large form in which it appears on telephones it’s sometimes called a square.

Recently, the hash sign has acquired a new role. On social networking sites such as Twitter, it’s attached to keywords or phrases so as to identify messages on a particular topic (e.g. #volcano; #Iceland). These keywords or phrases are known as [hashtags] (Oxford Languages | The Home of Language Data). Oxford Languages | The Home of Language Data

I personally usually refer to it as ‘hashtag’ although I know that this is not what it used to be called originally.

I call it the “pound sign” if there is not other context. Maybe from answering machines that always ask me to “press pound”.
