Short answer: no—unittest.mock.patch itself is not inherently thread-safe, and there are only limited ways to make things effectively safe depending on what you mean by “thread-safe”.

Why patching is not thread-safe

patch() works by mutating global/module-level state (replacing an attribute with a mock, then restoring it later) .

That creates a few problems in multithreaded scenarios:

Global mutation: While a patch is active, all threads see the patched object.
Timing/race issues: If multiple threads start/stop patches concurrently, they can overwrite or restore each other’s changes unpredictably.
