Both pensar and creer can translate to “think” in English, but they aren’t the same. Pensar is about the process of thinking or having an opinion. Creer is about believing something to be true.
The Short Version
- Pensar = to think (process), to plan, to be of the opinion that
- Creer = to believe, to think (with a sense of conviction or assumption)
Pensar: Thinking as a Process
Use pensar when someone is actively thinking — working through something, forming an opinion, or making a plan.
Active thinking
- Piensa antes de hablar. — Think before you speak.
- Estoy pensando en eso. — I’m thinking about that.
- ¿En qué piensas? — What are you thinking about?
- Necesito pensar. — I need to think.
Expressing an opinion (pensar que)
- Pienso que tienes razón. — I think you’re right. (My opinion.)
- ¿Qué piensas del plan? — What do you think of the plan?
- Pensamos que es una buena idea. — We think it’s a good idea.
Making plans (pensar + infinitive)
Pensar + infinitive expresses intention — what you’re planning to do:
- Pienso ir a Madrid el próximo verano. — I’m planning to go to Madrid next summer.
- ¿Qué piensas hacer? — What are you planning to do?
- Piensan abrir un restaurante. — They’re planning to open a restaurant.
Thinking about something fondly (pensar en)
- Siempre pienso en ti. — I’m always thinking of you.
- Piensa mucho en su familia. — He thinks about his family a lot.
Creer: Belief and Assumption
Use creer when someone holds a belief, makes an assumption, or states something with personal conviction.
Believing something is true
- Creo que está cerrado hoy. — I think it’s closed today. (I assume / believe it is.)
- No creo que sea cierto. — I don’t think that’s true. (Note: subjunctive after negative creer.)
- ¿Crees en los fantasmas? — Do you believe in ghosts?
Religious or ideological belief
- Creen en Dios. — They believe in God.
- No creo en esas teorías. — I don’t believe in those theories.
Assuming without certainty
- Creo que son las tres. — I think it’s three o’clock. (Best guess.)
- ¿Dónde está María? — No sé, creo que está en casa. — Where’s María? — I don’t know, I think she’s at home.

The Subjunctive After Creer
One practical difference: creer que in the negative triggers the subjunctive:
- Creo que viene mañana. ✓ (positive → indicative)
- No creo que venga mañana. ✓ (negative → subjunctive)
Pensar que follows the same pattern:
- Pienso que es verdad. ✓
- No pienso que sea verdad. ✓
How Native Speakers Use Them
In casual speech, creer is often the default for both “I think” and “I believe” — it’s shorter to say and covers both meanings loosely. Pensar gets used more when you want to emphasize the reasoning process, or when talking about plans.
- ¿Viene Juan? — Creo que sí. — Is Juan coming? — I think so. (Most natural here.)
- ¿Qué piensas hacer con tu vida? — What are you thinking of doing with your life? (Planning, not belief.)
