Mayonnaise are a five-piece Filipino alternative rock band, fronted by Monty Macalino and famous for winning the "Red Horse Muziklaban" contest in 2004.

The band were named after the song "Mayonaise" by The Smashing Pumpkins[1] and were formed in 2002 with a number of earlier former members until they settled with the four-piece lineup of Monty Macalino, Paga Manikan, Lee Maningas and Shan Regalado.

Popularly known as a 4-piece group, Mayonnaise announced its 3 new members shortly after Manikan's departure through their official social media accounts: Aaron Brosoto, Carlo Servano and Jaztin Mercado, who all used to play with them as session musicians on guitars and keyboards.

In November 2017, guitarist and backing vocalist Maan Furio amicably left the band to pursue a professional career in Dubai, UAE.

The song "Jopay" experienced a resurgence in popularity after becoming viral on Tiktok in late 2022 and early 2023,[7] attributed to its use as part of the soundtrack of the 2022 film Ngayon Kaya.
