The Latin Alphabet has Phoenician origin and it passed indirectly to the Latins: Greeks were the first to adapt and modify the alphabet from Phoenicians and then they passed it to the Etruscans, who they also modified it. Latin Alphabet uses both Etruscan and Greek elements but it was further modified by the ancient Romans to write the Latin language.
However, both Greek and Latin alphabets have significant differences from the Phoenician, which for example had only consonant sounds. Greeks modified the scripts so that they would represent vowel phonemes as well.
The Phoenician alphabet appeared around the 11th century BC and it is believed, without any significant proof, that it is relevant to the Egyptian hieroglyphs through the Proto-Sinaitic alphabet.
