Czech male names come from the Czech language, a West Slavic tongue, and long-standing Christian naming influenced by saints. Many traditional male forms are Slavic compounds with elements like -slav or -mír (for example Boleslav, Čestmír). Diminutive masculine forms ending in -ek, -ík, or -ouš/-uš are frequent in everyday use and are sometimes given officially. Czech orthography with diacritics (á, é, í, ý, č, š, ř, ž) is standard in male names.

In modern practice, official records usually use the full forms, while nicknames remain common in speech. Enduring male staples include Jan, Jiří, and František, alongside Bohumil and Čestmír, with Honza, Jenda, Jindřík, and Evženek as familiar diminutives.
