In the US, another way to make anonymous donations to charity is to use a Donor Advised Fund [1]. For example Fidelity Charitable [2] makes it easy to make grants anonymously if you choose.

Beyond that, there can also be additional tax advantages to giving to giving via DAF, especially if you have appreciated stock, bitcoin, etc. [3]
