"Rockaria!" is a song by Electric Light Orchestra (ELO), written by Jeff Lynne. It was the third track on the band's successful 1976 album, A New World Record and was the second single from the album. On some CD pressings of A New World Record, it appears without the exclamation point.

Featuring the operatic voice of Mary Thomas during the introduction, on the first recording take, she mistakenly started the vocals too early. However, Lynne elected to use the take (complete with her interjection, "Oops!") anyway (although some later pressings of the album are missing this part). During live performances, the 'aria' was provided by the band's bassist Kelly Groucutt, illustrating his wide-ranging vocal talents.

The song itself is a unique fusion of rocking blues, glam rock, opera and power pop. According to the lyrics, a woman is obsessed with the operatic masterworks of Wagner, Beethoven, Puccini and Verdi and the singer's intent is to show her how to rock and roll. By the end of the song, however, the twist becomes that the opera singer has proven that she actually can rock 'n' roll with the best of them and that she has a few tricks to teach to the singer. When Beethoven is mentioned, the opening of his Fifth Symphony is heard on the piano.

The title of the song is not used within the lyrics, thus it is often mispronounced, usually as rhyming with "diarrhea". It is actually a fusion of two different words, rock and aria, thus giving rock-ahr'-ia.

"Poker" is a song written and performed by Electric Light Orchestra.

The song first appeared on the band's LP, Face the Music as track number 5, It is the shortest song in length at 3:34, off the Face the Music LP. During recording, Kelly Groucutt sang most of the song's lyrics. (Normally, Jeff sang the vocals.)
