Secondary Riders (２号ライダー, Ni-gō Raidā), also known as Second Kamen Riders (2nd 仮面ライダー, Sekando Kamen Raidā), are a subset of Supporting Riders that receive second billing in each installment of the Kamen Rider Series.

It is important to clarify that the Secondary Rider isn't necessarily the second debuting Rider or hold the second most significant role in the series' storyline. During production, Secondary Riders are identified to have the second largest focus on the marketing for toys and products, coming after the Primary Rider.

The original Hayato Ichimonji/Kamen Rider 2 replaced Takeshi Hongo/Kamen Rider 1 for a portion of the original Kamen Rider before the two teamed up afterwards.

Notes

The name "2号ライダー" is also used to colloquially refer to Kamen Rider 2 himself, as much as Kamen Rider 1 is referred to in a similar vein as "1号ライダー".
Although Toei has now confirmed Kamen Rider Garren to be the secondary Rider of Kamen Rider Blade,^[19]^[20]^[21] the position was long debated to also belong to Kamen Rider Chalice due to Ryoji Morimoto having top billing over Kousei Amano during the show's run, even though other sources had already considered Chalice a "tertiary" Rider then.^[22] Furthermore, promotional posts for Kamen Rider Zi-O: Over Quartzer^[23] and the packaging for the Rider Card Archives Neo 2 set displayed Chalice amongst the Secondaries.^[24]
The position of Secondary Rider has been predominately male, a record which was broken with Kamen Rider Majade, the franchise's first official female Secondary Rider.
