Benjamin Franklin once said, “An investment in knowledge always pays the best interest.”

That’s never been truer than it is today. With new technology emerging at breakneck speeds, there's a palpable pressure to continuously upskill.

Whether you want that job promotion or to sidestep into a new field, you'll need to commit to learning new skills.

Of course, if you want to become an expert -- well, that takes even longer.

Blog posts and podcasts are great starting points for exploring a particular topic. But online business courses will provide you with the time and space you need to go deep and truly master a new skill. Plus, most courses are made up of on-demand videos and exercises that you can progress through at your own pace.

Below, we've gathered 60 of the best free online business courses. These cover the main business skills you'll need to advance in today's rapidly changing workplace -- from digital marketing and coding to selling, leadership, and more.
