I took a course on Latin poetry in university (my undergrad major was Classics) and out of that I got a couple favourite poets.
Quintus Horatius Flaccus, known in English just as Horace, wrote poems that were mostly on the shorter end. Some were reflective, some satirical. His Odes are probably his best work, or at least my favourites, but his Epistles get into a bit more detail of his philosophy (he was basically an Epicurean).
Publius Virgilius Maro, aka Virgil, is best known for his epic The Aeneid, especially the romance of Aeneas and Dido which forms the fourth chapter. He also wrote the Georgics and the Eclogues, shorter, more pastoral works.
The two knew each other and were part of a circle of poets around Maecenas, who functioned as kind of Augustus Caesar's minister of culture.
Eight of Horace's odes with both English translations and the Latin original:

Virgil's Georgics in English translation:

For The Aeneid, I am fond of Robert Fitzgerald's translation which is still available in print and ebook, I think.
