You’re leaving dinner with a Spanish host family, and everyone starts saying goodnight. You want to say something warm and natural, not just a flat translation from English. The trouble is, Spanish has several phrases that all mean something close to “good night” or “have a good night,” and they are not interchangeable.

From its community of 30,000+ tutors across 150+ languages, italki has Spanish teachers who help learners master these subtle distinctions in live conversation. This guide covers the main phrases for saying good night in Spanish, how each one differs, when to use them, and how register and region shape your choices.

How Spanish handles “Good night” differently from English

English draws a clear line between “good evening” (arriving) and “good night” (leaving or going to bed). Spanish does not make that split. The same phrase, buenas noches, covers both moments. You say it when you walk into a restaurant at 8 p.m. and again when you leave at 11 p.m.

The main phrases and how they differ

Buenas noches

Buenas noches (good night / good evening) is the baseline phrase every learner needs first. It is a complete, polite greeting or farewell that works in any situation, formal or informal, with strangers or with family. For a companion guide on Spanish greetings, see how to say hello in Spanish.

Que tengas buena noche

Que tengas buena noche (have a good night) is a direct farewell wish that specifically refers to the hours ahead. The verb form shifts depending on who you are speaking to: que tengas (informal, tú) versus que tenga (formal, usted).

Que descanses

Que descanses (rest well / have a good rest) is one of the warmest and most natural farewells in Spanish. It literally means “may you rest” and carries a tone of genuine care. Say it at the end of a long day, after dinner, or when someone has been working hard. Particularly common in Spain.

Que duermas bien

Que duermas bien (sleep well) is more specific than que descanses. It is a bedtime expression, said to someone who is about to go to sleep. Parents say it to their children. Partners say it to each other. The formal form: que duerma bien.

Dulces sueños

Dulces sueños (sweet dreams) is affectionate and informal. It belongs in close relationships: parents and children, romantic partners, or very close friends. Using it with an acquaintance or colleague would feel overly intimate.

Hasta mañana

Hasta mañana (until tomorrow / see you tomorrow) functions as a “good night” phrase in practice. It is casual, friendly, and very common among people who will see each other the next day.

Build flexibility with these six expressions. Work with a Spanish online tutor and practice code-switching between formal buenas noches and warm que descanses depending on who you’re talking to.
