Park Se-in
Overview
Park Se-in (박세인) is a Korean-style personal name that combines Park (박, 朴), one of Korea's representative surnames, with the given name Se-in. Rather than a proper noun referring to only one specific person, it is a name shared by namesakes in various fields, including actors, models, directors, athletes, and ordinary individuals, and its meaning and search results vary greatly depending on the Hanja and Romanization used. Since the 1990s, amid a preference for two-syllable names and a trend toward soft phonology, it has established itself as a relatively modern-sounding name, and in the 2020s it became a type of name attracting attention again alongside short-form and SNS-based self-branding.

Structure and Meaning of the Name
The surname Park (박, 朴) is a representative Korean surname originating from Park Hyeokgeose (박혁거세), the founding progenitor of Silla, and together with Kim (김, 金) and Lee (이, 李), it ranks at the top in population. The given name Se-in can be written in various ways in Hanja, such as 世仁 (benevolent in the world), 世寅, 世印, 洗仁, and 細仁, and it is not uncommon to register it as a native Korean name without using Hanja. Phonologically, the initial sound ㅅ is followed by two syllables without final consonants, giving it a soft pronunciation, and it is evaluated as a structure that is easy for foreigners to transliterate into Roman letters. In actual usage, it is written variously as Se-in, Sein, and Se In.
Naming and Registration
When registering a name in Korea, the surname, family clan seat (bon-gwan), and the range of Hanja permitted for personal names are subject to relevant regulations. The Supreme Court's Family Relations Registration Rules stipulate Hanja for personal names, and the usable Hanja have been expanded through amendments. Traditionally, naming was done by considering sound and the five elements, numerology, and saju (Four Pillars of Destiny), but recently there is a tendency to also consider sound and image, the convenience of English spelling, and the availability of online account handles. Se-in belongs to the category of names that are relatively safely chosen under these conditions.
Population Distribution and Statistical Characteristics
As of the 2015 Population and Housing Census, Park is the second most populous surname after Kim, with over approximately 4 million people counted. The name Se-in tends to appear evenly among those born from the late 1980s to the 2000s rather than being overly concentrated in a particular generation, and it has a gender-neutral impression used for both women and men. For this reason, it is difficult to determine gender definitively without also checking the Hanja spelling.
Namesakes and Disambiguation Practices
In search environments, Park Se-in is a representative namesake search term in which multiple people appear at the same time. Since occupational groups such as actors, models, directors, sports players, and creators often do not overlap, portals and wikis have established the practice of distinguishing them by listing birth year, occupation, and affiliation together. With the introduction of knowledge panels and structured data, the method of separating namesake documents and placing a notice at the top has also become common.
Recent Trends
As of 2024–2025, cases in which the name itself functions as a search brand have increased. As personal channels and portfolio sites became more active, the strategy of using stage names or English spellings alongside the name to distinguish between namesakes spread, and the trend of using the Korean name as is while unifying the Romanization also strengthened. At the same time, as generative search and AI summarization features became widespread, the phenomenon in which which person is summarized first when searching by name alone affects an individual's online reputation became pronounced. Accordingly, registering accurate identifying information in structured data such as Wikidata and knowledge graphs has become important, and combined with the naming trend of preferring Korean names over Hanja names, the issue of disambiguating namesakes is expected to become more complex in the future.
