{{As of|September 2024|url=https://trimet.org/bus}}, TriMet operates 75 bus routes (plus five routes that replace the MAX light rail service in late-night hours).<ref name="Bus Schedules">{{Cite web |title=TriMet: Bus Service |url=https://trimet.org/bus/index.htm |access-date=November 21, 2024 |website=}}</ref> Each route is identified by both a number and a name. The numbers are mostly in the range 1–99, but there are currently eight routes with three-digit numbers.<ref name="Bus Schedules" />  From 1969 until 1973, TriMet bus routes were named but not numbered, a practice inherited from [[Rose City Transit]] and the [[Blue Bus lines (Oregon)|"Blue Bus" lines]], but route numbers were assigned to all routes in August 1973.<ref name="oreg-1973aug7">{{Cite news |date=August 7, 1973 |title=Tri-Met directors discontinue little-used experimental route |work=The Oregonian |page=15}}</ref><ref name="ad-1973aug">{{Cite news |date=August 28, 1973 |title="Take a number ....

Seventeen bus routes are designated as "Frequent Service Lines", which the agency defines as having a [[headway]] of 15 minutes or less most of the service day (service is less frequent in the early morning and late evening).<ref name="FrequentService">{{Cite web |title=TriMet: Frequent Service Lines |url=https://trimet.org/schedules/frequentservice.htm |url-status=live |archive-url=https://web.archive.org/web/20190109065214/https://trimet.org/schedules/frequentservice.htm |archive-date=January 9, 2019 |access-date=September 12, 2015}}</ref> Fifty-eight percent of all bus trips are on the frequent service lines.<ref name="FrequentService" /> Bus stops that are served by a frequent service line are identified with an additional green sign.

The bus system includes [[List of TriMet transit centers|15 transit centers]], that allow passengers to transfer between bus routes and, at many transit centers, MAX routes.

TriMet buses began carrying bicycles on the front in 1992, on a trial basis on eight routes;<ref name="oreg-1992jun18">{{Cite news |last=Walker |first=Dee J. |date=June 18, 1992 |title=Tri-Met to kick off one-year trial of bike project |work=The Oregonian |page=C6}}</ref> the experiment was judged a success and within three years the entire bus fleet had been fitted with bike racks.<ref name="oreg-1995feb21">{{Cite news |date=February 21, 1995 |title=People will bike, walk (editorial) |work='The Oregonian |page=B6}}</ref>

TriMet added a temporary free shuttle service connecting between [[Rose Quarter Transit Center]] and a temporary bottle redemption facility in industrial district in Northwest Portland specifically to address people redeeming empty containers while grocers have been relieved from the [[Oregon Bottle Bill]] during the [[COVID-19 pandemic]]. This service was created at the request of Governor [[Kate Brown]]<ref>{{Cite news |last=Mesh |first=Aaron |title=TriMet Launches a Bus Line to Take People to Return Bottles and Cans |url=https://www.wweek.com/news/2020/04/26/trimet-launches-a-bus-line-to-take-people-to-return-bottles-and-cans/ |url-status=live |archive-url=https://web.archive.org/web/20200502125155/https://www.wweek.com/news/2020/04/26/trimet-launches-a-bus-line-to-take-people-to-return-bottles-and-cans/ |archive-date=May 2, 2020 |access-date=April 30, 2020 |work=[[Willamette Week]] |language=en-US}}</ref> and it went into service on April 29, 2020.<ref>{{Cite news |date=April 29, 2020 |title=Most Portland stores stop accepting bottle returns; TriMet creates free shuttle to bottle drop |url=https://www.kgw.com/article/news/health/coronavirus/trimet-shuttle-can-returns-bottle-deposit-obrc/283-e64a7313-38d0-4de0-8375-6dc732ecbf21 |url-status=live |archive-url=https://web.archive.org/web/20200505224752/https://www.kgw.com/article/news/health/coronavirus/trimet-shuttle-can-returns-bottle-deposit-obrc/283-e64a7313-38d0-4de0-8375-6dc732ecbf21 |archive-date=May 5, 2020 |access-date=April 30, 2020 |publisher=[[KGW]]}}</ref>

On September 18, 2022, TriMet started its [[Frequent Express|FX (Frequent Express)]] service, a [[limited-stop]] bus route with some [[bus rapid transit]] features. FX replaced the 2-Division, the sixth busiest bus route in the system, and features [[articulated buses]], all-door boarding, [[transit signal priority]], [[bus lane]]s and frequent service (12-minute [[headways]] all day).<ref>{{Cite news |last=Hasenstab |first=Alex |date=April 5, 2022 |title=TriMet starts driver training on super-sized buses along Division Street |url=https://www.opb.org/article/2022/04/05/trimet-starts-driver-training-on-super-sized-buses-along-division-street/ |url-status=live |archive-url=https://web.archive.org/web/20220619042840/https://www.opb.org/article/2022/04/05/trimet-starts-driver-training-on-super-sized-buses-along-division-street/ |archive-date=June 19, 2022 |access-date=June 22, 2022 |work=[[Oregon Public Broadcasting]] |language=en}}</ref>
