Steam shows every game you've ever bought or received as a gift in its library. It remembers some free games you've installed, too. But you can hide a game from your library – or even delete it permanently from your account.
The difference between hiding and removing games
Hiding is reversible. When you hide a Steam game, it is hidden from the default library views. Someone can still see the game with a few clicks, and you can distinguish the game in the future. You can even play a hidden game. It's just one way to sweep a game under the carpet at the moment.
Delete is permanent. Removing a game from your Steam account permanently removes it. The game will not appear in your library. You need to contact Steam customer support before and ask for it, but there is now a common way that you can remove games in a few clicks. Be careful: To play the game again in the future, you must repurchase it.

How to remove a game from your steam account

Click "I want to permanently delete this game from my account." (If you purchased the game in the last two weeks and played it under less than two hours you can also return the game for repayment from here.)
