The Metropolitan Transportation Authority (MTA) operates a number of bus routes in Staten Island, New York, United States. Some of them are the direct descendants of streetcar lines (see list of streetcar lines in Staten Island). Many routes run to the St. George Terminal, at St. George in northeastern Staten Island, where there are connections to the Staten Island Ferry. The fare, payable by MetroCard, coins, or the OMNY contactless payment system, is $2.90 as of 2023. Discount fares are available.

Local Service

S79 Select Bus Service

Operated as a Select Bus Service (SBS) route. The S79 provides SBS service at all times. Originally a local route, the S79 was converted to an SBS route in 2012, with the number of stops cut by about three-quarters. But unlike the SBS buses in the rest of New York City, the S79 has no fare machines at bus stops, so fares are collected onboard the bus.

Limited-Stop Service

All limited-stop services, except for the S89 and S93, duplicate the routes of their respective local services. The S93 runs weekdays from 6:00am to 10:00pm. Other routes run weekday rush hours only.

Bus route history

Except for the S61, all current Staten Island bus routes originally had different designations before they were renumbered by service patterns, as follows: On April 2, 1989, routes on the North Shore of Staten Island were renumbered. The implementation of this numbering scheme was completed on April 15, 1990, when the final eight routes, all from St. George, were renumbered. Old and new routes are given below, along with discontinued service patterns. In addition, before 1975, routes were designated with R (for Richmond, the borough's official name before 1975) instead of S. The R designation is shown in the "Old Route" section.
