Quick Answer:
Mindfulness is a quality of awareness — paying attention to the present moment without judgment — that you can bring to anything, from eating to walking. Meditation is a formal practice for training that awareness. Put simply: mindfulness is the skill, and meditation is the gym where you build it.
Two Related but Distinct Things
Mindfulness is a way of paying attention — being fully present, aware, and non-judgmental. You can be mindful while washing dishes, walking, or listening to a friend. Meditation is a deliberate practice (like breath meditation) where you set aside time to train attention.
How They Relate
Meditation is how you strengthen the "muscle" of mindfulness. The more you practise formal meditation, the more easily mindfulness shows up in daily life. Not all meditation is mindfulness-based (concentration and loving-kindness practices exist too), and you can be mindful without ever formally meditating — but the two reinforce each other beautifully.
Which Should You Start With?
For most beginners, a short daily meditation practice is the easiest on-ramp — it builds the skill you then carry into everyday mindfulness. Guided meditation apps make it simple to begin.
