Latvian male names come from Latvian, a Baltic language. The standard masculine nominative ending is -s or -š, with -is also common, so foreign names are adapted to these endings (for example, Aleksandrs, Nikolajs). Native orthography uses diacritics such as ā, ī, ū, č, š, ģ, ķ, ļ, ņ, ž.

Male naming draws heavily on Christian and European forms alongside Baltic-origin names. Today, parents often use concise, Latvianized variants and retain the masculine endings in official records. Common examples include Kristaps, Matīss, Miks, Aivars, Armands, Guntis, Guntars, Nikolajs, Pavils, and Ritvars.
