nameparser parses human names into seven fields — title, given, middle, family, suffix, nickname, maiden. Results are immutable, configuration is composable, and locale packs are opt-in.

📣 nameparser 2.0 is out. Existing HumanName code keeps working through 2.x, and most 1.x code needs no changes. The migration guide has the field-by-field map. Please open an issue for anything that parses wrong.

2.1 adds East Asian name support. Chinese, Japanese and Korean names written in their own scripts are read family-first, unspaced Korean names are split against the census surname list, and CJK honorifics are recognized. See East Asian names.

Installation

pip install nameparser

Requires Python 3.11+.

Quick Start Example

>>> from nameparser import parse
>>> name = parse("Dr. Juan Q. Xavier de la Vega III (Doc Vega)")
>>> name
<ParsedName: [
    title: 'Dr.'
    given: 'Juan'
    middle: 'Q. Xavier'
    family: 'de la Vega'
    suffix: 'III'
    nickname: 'Doc Vega'
]>
>>> name.family_base, name.family_particles
('Vega', 'de la')
>>> name.given_names, name.surnames
('Juan Q. Xavier', 'Q. Xavier de la Vega')
>>> name.render("{family}, {given}")
'de la Vega, Juan'

>>> parse("김민준").family                     # Korean: unspaced, split on the census list
'김'
>>> parse("高橋 みなみ").family                 # Japanese: kanji with kana, family first
'高橋'
>>> parse("김민준씨").suffix                   # an honorific written against the name
'씨'
>>> parse("г-н Иван Петров").title             # Cyrillic title
'г-н'
>>> parse("محمد بن سلمان").family              # Arabic: بن chains onto the family name
'بن سلمان'

>>> from nameparser import locales, parser_for
>>> chinese = parser_for(locales.ZH)           # Han text does not say which language
>>> chinese.parse("毛泽东").family              # so splitting it is opt-in
'毛'
>>> russian = parser_for(locales.RU)
>>> russian.parse("Сидоров Иван Петрович").family
'Сидоров'
>>> locales.available()
('ja', 'ru', 'tr_az', 'zh')

  • Using the parser — the full tour: input shapes, aggregates, rendering, comparison, ambiguities, tokens

  • Customizing the parser — vocabulary, behavior, and presentation

  • Locale packs — opt-in bundles for East Slavic patronymics, Turkic markers, and more

  • There’s also a CLI: python -m nameparser --json "Doe, John"

Coming from 1.x

HumanName and CONSTANTS keep working in 2.0 — same imports, same attributes, same mutation API. What 2.0 removes is the batch of deprecations 1.3 and 1.4 announced, so if your test suite runs clean on 1.4 under python -W error::DeprecationWarning, you are nearly done. Two things that check will not catch: four removals 1.4 never warned about (three raise on contact, the fourth only warns), and one that changes results silently — name == "John Smith" is now False. Migrating from HumanName covers both, and translates a v1 customization into the new API whenever that’s convenient for you.
